Pembleton and Bayliss have only twelve hours to grill their prime suspect in the Adena Watson case before they must let him go.

A man falls between the cars of a subway train in front of horrified witnesses. Was he pushed? While the man is still alive, the prognosis is he will be dead the moment they extract from the position he currently occupies: pinned between the train and platform. Homicide is called in light of this condition and the fact he may have been pushed. Pembleton questions the victim, and Bayliss questions the witnesses, especially a strange one named Larry Biedron. The victim has no relatives in the Baltimore area. He does have a girlfriend who is supposed to be jogging in the area; Lewis and Falsone try to find her to bring her to the scene.

The search for Georgia Rae and the war against her organization begin. Stivers, uncomfortable with the whole situation tells Gee about the Luther Mahoney shooting. Ballard and Gharty begin to deal with their recovery. A lead on Georgia Rae's whereabouts is uncovered. During the assault on the building, Georgia Rae's body is found and Bayliss takes a bullet that would have hit Pembleton. Gee asks Pembleton to get to heart of the Luther Mahoney shooting that started it all. Pembleton and Falsone start with Lewis and then they move onto Kellerman. The truth about the shooting comes out and Kellerman claims sole responsibility, Pembleton asks him for his badge. To protect Stivers and Lewis from prosecution, Kellerman resigns. Feeling remorse for the hesitation that caused Bayliss to take a bullet for him and with Gee's plans to cover-up the truth about the Luther Mahoney shooting, Pembleton decides it is time to resign.

Bolander, Munch, Howard and Felton all meet to serve a warrant, but Bolander, Howard and Felton are shot in an ambush. Pembleton becomes the primary in the investigation and is partnered with a detective who specializes in the psychology of their prime suspect: a pedophile. Stan's ex-partner Mitch Drummond offers his help. Kay's father and Beau's wife and the kids come to the hospital. A clerical error is discovered to be the cause of why the detectives went to the door marked 201, instead of 210.

Judge Gibbons has been stabbed. On their way to the crime scene, Bayliss and Pembleton talk about a book that Bayliss is reading, then Pembleton wonders if anyone would ever write a book about their Homicide unit. A probation officer is murdered in a drive-by shooting. The FBI gets involved with investigation of the Gibbons death. Agent Bauer mentions to Bayliss that Kellerman's confrontation with Gibbons probably got the judge killed. He wants Kellerman clear of the case. A fingerprint lifted from the Gibbons' crime scene points to Georgia Rae's son, Junior Bunk. Falsone and Stivers get a lead on their probation officer shooting case. As Junior Bunk is brought in for questioning, he eyeballs a handgun being put in a drawer. Pembleton and Bayliss get Junior in the box and he is no longer able to be intimidated. While waiting to be transferred to central booking, Kellerman, Lewis & Gharty harass Junior. Slightly freed up to make a phone call, Junior gets the gun out of the desk and begi

Crosetti's body is found and Bolander is the primary and he thinks the evidence points to suicide. If it is a suicide, there will be no honor guard for the funeral. Refusing to accept the death as a suicide, Meldrick launches his own investigation and tries to thwart Bolander's investigation. Bayliss and Pembleton make arrangements for the funeral reception. Pembleton has reservations about going into the church for the services. Munch works with his brother, an undertaker, to arrange for a coffin. The preliminary ME report shows Crosetti had a blood alcohol level of .25 and wide variety of anti-depressants, The verdict: suicide.

Mike and Julianna wake up the morning after a night of drinking and passion. The investigation into Beau's death continues; Howard wants to be the primary while Frank tries to maintain control. Gee asks her to step aside and let him do the job with a more unbiased approach. The investigation creates some unlikely pairings: Pembleton with Gharty and Bayliss with Falsone and Munch on his own. Meanwhile, Howard and Russert make arrangements for Beau's funeral. Lewis and Kellerman's investigation into a homicide is stalled; when Kellerman's hangover laden police work is shoddy. When it appears as thought the investigation is going nowhere; Kay demands to be put on the case. Gee refuses. Because of his bad day and finding Julianna drinking with someone at the Waterfront Bar, Kellerman suggests that they should stop drinking. Frank tries to call Mary; eventually they connect and reconcile; with Frank saying that he is willing to give it all up. They find out who killed Beau, but when they go

Jay Leno stops by the Waterfront Bar while in town visiting his cousin Mary; Munch and Bayliss don't want to bother him. A new year starts out with a clean board and Brodie begins his work taping with the detectives. A sniper takes the city hostage, threatening to and executing people every 8 hours. The sniper uses Hangman as a way to leave clues for the detectives. Bayliss is the primary and his back is giving him trouble as he worries about surgery his doctor wants him to have. To combat the pain, he keeps taking muscle relaxants. A suspect is found and cornered and he shoots himself before they can take him into custody. Russert gets demoted when Barnfather doesn't like the way she handled the investigation.

The detectives continue chasing their only lead, the child molester. Munch is teamed with Stan's old partner. Beau has no feeling in his foot, but feels guilt about Kay's condition. Stan's ex-wife arrives in town, but has a hard time going to see him at the hospital. Barnfather and Granger want Russert to review Gee and see if he was negligent in his duties regarding the paperwork that led to the shooting. The pedophile is located and it is discovered he was responsible for the strangulation of a young boy, but not the shooting of the three detectives.

Things begin to heat up between Pembleton and Gee over the alleged police brutality case and one of the suspects is an ex-lover of Kay's. Bolander meets a waitress who encourages him to resume his cello playing. Munch's girlfriend is less than enthusiastic when he surprises her with a new fish for her tank. Frank, in the box, gets the confession that Gee is looking for. Unfortunately, the suspect is anything but guilty of that crime.

Bayliss has disappeared again as Pembleton and Brodie make their way to the scene of a shotgun suicide. The victim appears to be Beau Felton. Gee's letter, including information gained in the ""Burundi"" case, begins to make an impact at the highest levels of the department. Frank returns to the department with the news about his case. Lewis goes off, wondering who is going to be next. Det. Falsone comes to the squad with news about why he thinks Beau Felton killed himself. Lewis and Stivers discuss the Mahoney shooting. Cox finds something interesting about the Felton case; she digs in deeper and the results change the case to a murder. Bayliss turns up the next day and disappears again to his Uncle George's place. Pembleton and Howard try to work with Falsone to find Beau's killer. Gee finds out that Beau had been working undercover for the past six months on the Cantwell auto-theft ring. Megan Russert returns from France.

On New Year's Eve, the detectives sit back in the quiet of the evening and watch a documentary that Brodie has made about them and their work. In this documentary, entitled ""BACK PAGE NEWS: Life and Homicide On The Mean Streets Of Baltimore"", one of Frank and Tim's cases is covered where some ""lies and hidden truths"" are revealed. During a sequence about one of Mike and Meldrick's cases, they chase a suspect right into the filming of something called ""Homicide"" by director Barry Levinson and his crew. Mike and Julianna agree to try a date. Also, the identity of the ""lunch bandit"" is revealed to be Gaffney. Brodie reveals that the documentary has been sent to PBS and gives his reasons why. As the new year rolls in, things return to normal as the phones start ringing.

The Wilsons go on television to offer a reward. The newspapers are making the Homicide unit look bad and Barnfather wants quick resolution to the case. The man (and his wife) who gave up Junior Bunk are murdered; Falsone and Lewis investigate. The only survivor, their young son, is brought in to find out what he remembers. His memories-- and a recorded phone message-- lead Stivers to believe a former member of the Narcotics unit is involved. The officer cops to a deal that implicates Georgia Rae Mahoney, though Giardella doesn't want to pursue that yet. Falsone's questioning of the Mahoney shooting leads Cox to doubt her actions at the time of the investigation. Incriminating evidence leads the detectives to Hal Wilson being their prime suspect. Frank goes to interview Felix and Hal Wilson; son and father confront some long-standing issues. Hal's confession is inadmissible in court, the Wilsons leave the Baltimore area, and the case remains officially open.

Their rotation in robbery is up, Frank and Tim return to the homicide unit. They find that citations are being handed out to the unit and a delighted Gee, whose clearance rate is the highest it has been in five years. Kellerman and Lewis are also scheduled to return. Howard is still on assignment with the fugitive squad. Additions to the unit through rotated assignment include Det. Ballard who actually comes from a Seattle homicide unit, Det. Falsone and Det. Gharty. Falsone and Gharty worked with the unit on the Felton case last spring; however, nothing is mentioned about the status of that case. (Sharp-eyed viewers note that Felton's name is still in red under Pembleton's name on the board.) Meanwhile, Gee attends a black tie function honoring Felix Wilson, a respected member of the community. Because he grew up with them, Gee sits at a table with Felix, his wife and their family. Everyone attending the function at the hotel is kept late because the body of a woman is found dead in t

A riot breaks out at the prison, where two inmates are killed. The squad goes to the scene, but Frank must still stay behind. Bayliss, Lewis, Kellerman and Howard interview the inmates; many of them have familiar faces. Frank works on his target practice. Bayliss thinks that one inmate really wanted to tell him something, so he puts together a deal to get the information. The inmate confesses to the murder and Bayliss doesn't believe him. Another riot breaks out and the truth is finally discovered.

The sniper continues the shootings and everyone returns to duty lacking sleep. The media starts to make their presence felt. Munch begins to worry about Howard's safety, fearing she'll be wounded again. Frank makes his wife wear a bulletproof vest. Gee asks for Russert's help even though Barnfather had ordered her to stand down during the rest of this investigation. A man at the scene of both of the day's shootings is put into the box for questioning. Russert has a talk with the suspect with the subject being keeping people's attention and respect.

There is a major police chase after an armed suspect, as he holes himself up in a row house that is the headquarters of ARM (African Revival Movement). The head of that house, a former cop, calls in a favor, high in the police department. Munch and Pembleton try to work the case as Bayliss seems to be missing. Their investigation seems to be thwarted every step of the way. Stivers' has second thoughts about what she saw at the Mahoney shooting. An attempt to serve ""Burundi"" Robinson an arrest warrant breaks out into a war between the police and ARM. Gee goes into the house to confront Robinson and finds out who and what he knows.

The deputy commissioner invites Pembleton to lunch and gets him to investigate a case involving a congressman. Beau hires a private detective to find Beth and the kids when his clue that they are in Wilmington falls through. Howard and Felton investigate a case of a dead homeless man. Their job is made more difficult when they can't find the body. Lewis and Munch investigate the death of a motorcycle gang member. Pembleton finds out the truth, participates in the cover-up and then resigns when the media gets hold of the real story and the deputy commissioner doesn't back him up.

A woman that Munch had a crush on in high school is found murdered. He struggles with his faith as he works with Kellerman on the case. Meanwhile, Frank also struggles with his faith and the fact that Mary has left him.

Mary gave birth to a girl named Olivia; Tim is more excited about it than Frank. Their latest case involves a multiple shooting a restaurant. Lewis is back from his honeymoon, but while working a case with Kellerman, he confesses that they have yet to consummate their marriage. Later he tells him that they've separated. Tim stops by to see Frank and Mary's baby. They get a suspect for their case in the box. Frank collapses in the box while interrogating a suspect. Frank is put under the knife to release the pressure built up in his head from the stroke he had. After the surgery the doctor tells them that he doesn't know if Frank will recover.

A trash-talking radio talk-show host makes a proposal to his listening audience. Lewis announces to Kellerman that he is getting married today, then he throws up. He motivates the rest of the squad to help him with the final details as he is getting married ""tonight after the shift ends."" Kay brings her sister with her to the station. Since the whole squad is busy with Lewis' wedding, Gee takes Howard out to work the homicide of the radio talk-show host. One of his listeners took him up on his proposal. Munch is skeptical about the Lewis wedding; he thinks it's an elaborate practical joke. Bayliss and Kellerman vie for the attention of Kay's sister. Gee shoots and kills a potential suspect, but the suspect was in jail at the time of the talk show host's murder. The guy who fingered him admits that he did it as a joke. The wedding is no hoax. During the festivities Pembleton's wife goes into labor.

Pembleton and Bayliss investigate the shooting of a young boy. During the investigation, the mother of the victim meets the mother of the shooter in the aquarium. The shooter shows no remorse for the killing, although he shot the wrong kid. Munch, Bayliss and Lewis can't remodel the bar when they discover it's been classified a historical landmark. Then when they find out back taxes are due on the building, which shuts them down before they open. Beau finds out his kids are in Upper Darby, Pennsylvania, so he goes to find them.

Frank and Tim investigate the death of a young girl whose abused body was found by the side of the interstate. Brodie goes to an interview with a new potential roommate. Kellerman finally gets his day in court, where he is supposed to take the 5th amendment. Frank and Tim disagree with their pursuit of the investigation. Frank tries a different approach with the mother and she tells him the story-- only they won't be able to get a murder one conviction. Julianna comes down to the courthouse to offer Mike some moral support. He sees Connelly come out of the courtroom and thinks things are going bad, so he prepares to give it all up. However, his appearance before the grand jury doesn't go quite as he expected. Brodie walks out of the building with his new roommate. The detectives try to celebrate Kellerman's freedom, though he has different thoughts about the situation. Tim tries to come to grips with the child abuse he experienced in his past and also tells Frank he doesn't want to be

Bolander has a relapse. The detectives sound off to the local news about the shooting. Apartment 201 is opened up and the occupant, Gordon Pratt, is a gun freak who once tried to be a cop. Russert and Howard declare a truce. They find the shooter, but lack of a weapon gets him released; later he is found with a bullet in his head.

The fire investigation continues. Bayliss' back is acting up and Kellerman is paired with Pembleton. Kellerman shows Gee something, so he is offered a transfer into the department that he first rejects. Kay takes the sergeant's exam, Munch misses it due a ""comedy of errors.""

Frank gets his first case as a primary-- unfortunately it is a case that involves the shooting of Danver's fiancée. Danvers is concerned about Frank being the primary and keeps throwing his opinions into the investigation. Danvers changes his perspective on the death penalty and also reflects on his past performance in many of the cases he's tried. Brodie continues to look for housing; the latest place he tried staying was the morgue. Kellerman is discouraged when it appears as though Cox may have only been looking for a one-night stand and nothing more-- so he takes a sick day. Gee takes some time out of his day to have a talk with Kellerman's former partners to see where they stand with him in regard to their testimonies to the grand jury. He also sees the Deputy Commissioner to see what can be done for Kellerman; what he learns instead are some truths about the Gaffney promotion.

Tim's cousin shoots a Turkish exchange student and his partnership with Pembleton may be in jeopardy when they both stand on opposite sides of the case. Lewis hires his grandmother to cook at the bar.

Gee informs the detectives that they must meet with a sensitivity consultant. Felton protects a friend who's going to help his terminally ill father commit suicide. Pembleton investigates a routine murder that escalates into a case of possible police brutality. Bolander has no intention of meeting with the consultant to the point where he takes a suspension without pay. Lewis investigates the death of the father of Felton's friend and discovers the truth and confronts Beau.

The squad returns to the station. The FBI joins with the detectives to stop a ""thrill killer"" who's working his way north on I-95. Gee tries to reconcile with his daughter. The killer smells a rat at a roadblock so he bails out of his pickup. Everyone mobilizes to find him and when they do, the suspect in custody, while identical to the killer, claims he is innocent.

Family members of murder victims (Widmer, Rath and Silvio) are in a support group where they discuss their feelings about the loss they have each suffered. Short-handed, Gee investigates the Widmer homicide at the Waterfront Bar. Bayliss' homicide is unidentified for 48 hours before she is identified as being Rath. Lewis and Munch investigate a car jacking at Federal Hill, where the mother is the victim and the 3-year-old daughter in the car at the time is missing. Meanwhile, Howard, Kellerman and Pembleton stay behind. Frank interviews the two witnesses that Tim had in for questioning and gets a lead on a suspect. Cox joins the support group meeting late; she is still coping with the death of her father.

Brodie suggests that a classmate of his named Schack should be a suspect in the death of the student that Munch believes committed suicide. Frank and Mary meet with their marriage counselor and they begin to air some issues. Bayliss and Kellerman try to link together two deadly bombings. Schack attacks Brodie, but he can't prove it. He does offer a way to get Schack to admit to the murder. Frank tells Mary that he will agree to getting Olivia baptized. Mike connects the two bombings; the victims were both connected through the death of the Korean grocer who was murdered by a man who worked for Luther Mahoney. They suspect that there may be more bombs, including one at the courthouse where Meldrick and Julianna are waiting to meet with Judge Aandahl and Danvers, both of who were associated with the Korean grocer case. Frank arrives late to the baptism; Mary takes this as a sign and tells him she is leaving him for a while.

A convict is released from prison and begins to get his revenge on Frank by frustrating the investigation he is currently working on and also by terrorizing his wife.

All the detectives scramble to solve the case, when the mother, in a family on vacation, is murdered during a holdup. The husband has a hard time dealing with the reality of him not doing anything during the situation and Felton's indifference. When the suspects are found Howard is convinced that the youth who confesses to the murder didn't do it.

The semi-nude body of a man is found in a dumpster outside of a restaurant. Bayliss returns Cox a pair of her earrings that she'd left at his place the night before. Disturbed by him doing that in public and while at a crime scene, she suggests they take some time off, instead they decide to break it off. The owners of the restaurant thinks that this murder might be tied to another murder (one that Munch is working). Lewis confronts Kellerman about the Mahoney videotape and the need to let Stivers know that she is also ""in the soup."" Lewis tells Stivers about the videotape, so she demands a meeting with Kellerman. Falsone confronts his ex-wife about getting to see his son more often; however, they argue and he plans to pursue getting joint custody. Kellerman decides that he will try to force Georgia Rae's hand, since he doesn't plan on doing anything corrupt for her anyway. Kellerman tells Georgia Rae that she can do whatever she wants with the videotape, he doesn't care. Bayliss decid

A young man comes into the squad room and after getting their attention, tells the detectives that his brother has been shot. Pembleton is sued by the multiple personality serial killer, who states he violated her civil rights during interrogation; he is discouraged when the city agrees to settle out of court. Munch must attend an alcohol awareness seminar to meet a requirement for the bar. Lewis has ""love at first sight"" with a woman who makes models of crime scenes, but she has ""love at first sight"" when she sees Bayliss and he sees her. Later, they attend an art exhibition and have an unusual sexual encounter in her ""bed."" All is not well at the Felton household, when he returns home to a cleaned out house.

Bayliss suffers from a recurring dream about the Adena Watson, his first homicide case and one that remains unsolved. An elderly man comes to the Homicide unit to confess to Bayliss that his father had committed a murder 66 years ago. Falsone is assigned to the case, only the case file is missing and found to be in the possession of retired homicide detective, Thomas Finnegan. Gee allows Finnegan's request to participate in the reopened investigation. Questioning the elderly man leads to the recovery of the gun that might close the case. Falsone, Finnegan, Lewis and Kellerman celebrate their potential victory as Bayliss recontemplates the Watson case.

A man transporting 72 condoms filled with heroin bound for Luther Mahoney is found dead in hotel. The department takes this opportunity to set up ""Operation Get Luther."" The operation almost goes off as planned, except Luther Mahoney gets Lewis' gun and is holding it on him as Kellerman and Stivers enter. Frank and Tim agree to become partners again. Tim stops by to see his uncle. Munch takes a call from a convict who was looking to talk to Bolander. He has information on an old murder case that should be a done deal. That involves the digging up of section C of the parking lot at a racetrack. Munch discovers that the supposed victim is alive; however, he isn't that way for long.

The Internet is stage for a ritual murder, which was staged -- which was staged, or was it? The body is found the following morning and Sheppard takes the call, her first since the beating. Since Lewis can't be found, she partners with Bayliss. Second shift detectives Bonaventura and Austin catch word of the day shift's case. It seems the victim in Sheppard's case was a witness they had interviewed the day before about an online murder hoax. The detectives are informed about another murder that is scheduled for midnight. It's a red ball. The detectives try to put the clues together, but come up with nothing and must wait until the netcast begins before they can trace the killer. The trace is successful, but when they arrive at the scene, the killer has left them a computer with the words ""Ha Ha Fooled You."" Barnfather wants Bayliss reassigned as primary if something doesn't turn up soon. Sheppard goes online to flush out the killer. He advertises another murder will take place at www.i

A woman comes looking for Falsone, knowing that he solved a real old case, wants him to look into a case for her from 1972. Her parents told her that she was responsible for her younger brother's death. Despite being three years old at the time, the woman has doubts about her parents' story. So Falsone and Stivers reopen this case, which was closed by Gee when he was a new detective. The reopening of the case makes Gee think that he may not have been totally focused on the case at the time. Their investigation reveals the woman's mother used her as a scapegoat for the mother's crime. Bayliss and Ballard's case involves a body that was shot, but the victim was already dead from a drug overdose. The male sergeant at the scene piques Bayliss's interest, so they get together for drinks. Their relationship doesn't develop, because word is spreading about Bayliss being the owner of the ""In Plain Site"" web site. Bayliss begins feeling pressure about his being different and considers celibacy.

Lewis and Munch begin to investigate the death of a Buddhist monk beaten to death. Lewis isn't interested in working the case with Bayliss, whom he feels, may become too emotionally involved. Ballard and Falsone agree to call their relationship quits. Ballard and Gharty's case involves a man who was shot down in the street; the three witnesses that saw the shooter all have different recollections of his appearance. As a result, their prime suspect cannot be charged. Gee asks for Bayliss's assistance in the Buddhist murder and to Lewis's dismay, Munch abdicates his position in the investigation to Bayliss. Lewis and Bayliss take different approaches to the investigation. Bayliss's approach leads him to the man who committed the crime, but cornering his suspect leads to a showdown with guns and Bayliss fires a fatal shot. Later Bayliss tries to reconcile the shooting with his own feelings about being a Buddhist and being a cop.

Ballard and Bayliss are called to the scene of the mysterious death of a woman, whose body is found at the bottom of a forty-foot cliff. This victim was to be married the following morning. The two detectives work to determine whether the death was accidental or intentional (via murder or suicide). Meanwhile Sheppard and MGee begin investigating the death of a movie patron, whose body was discovered after the show ended and the theater cleared out. MGee mentions to Sheppard that his sister is about to have a baby, which means Gee is about to become a grandfather. Their investigation reveals that the movie patron was regularly loud and obnoxious and thus bad for business. When an overdose of a sedative is found in his bloodstream, the detectives question the theater owner, who was currently in litigation with the victim. Unfortunately for Ballard and Bayliss, their case remains unsolved.

A woman brings to the homicide unit her mystery-writer husband's videotaped declaration that his literary agent is responsible for his murder. Ballard and Gharty catch the case -- only there is no body or crime scene. Meanwhile, Munch and Bayliss investigate the death of an elderly woman that occurred during a break-in -- was it a homicide? Munch would rather leave for his weekend rendezvous with Billie Lou. Ballard and Gharty's investigation becomes a red-ball as they find evidence in the writer's office that a crime was committed. A break leads to the arrest of the literary agent and his accomplice, although Danvers can't guarantee a conviction. Falsone asks Ballard if she would like to go out Saturday night; just then the jury comes back. And a sharp-eyed juror insures that justice is done.

A body buried for 6 - 20 years is uncovered at a construction site. Munch and Lewis begin the process of trying to solve this old crime. Falsone and Ballard's relationship has heated up, and that fact becomes apparent to their fellow detectives. Sheppard returns to work, but is discouraged when Gee assigns her to desk duty. Gharty tells Billie Lou that he'll attend her bass-playing concert. Munch & Lewis with help from the ME and MGee, identify the body and then begin to piece together what happened to her. Gee lays down the law to Ballard & Falsone: they have to knock it off if they want to stay working on the same shift; they agree.

Lewis and Crosetti uncover a woman who's been killing her husbands for insurance money. Howard tries to keep her cases-solved record perfect, but she is reassigned with Felton as her partner. Bolander convinces Munch to help him finish up an unsolved case. A new guy, Tim Bayliss, from the mayor's office gets his first case in homicide, the murder of an 11-year-old girl. His partner Pembleton, we find out, is less than enthusiastic to work with him or anyone else in the unit.

Bounty hunters shoot, killing the wrong man, as they enter a building where their fugitive---a man named Joe Errico---has shot at them (and subsequently gotten away). Gharty has vague memories of a drinking binge from the night before. Falsone and Stivers catch the bounty-hunter case. Sheppard, during her days with the fugitive squad, had dealings with the head bounty hunter. Gaffney stops Gee and MGee on their way in, Baltimore magazine wants to do a father and son piece, using the wine case as a focal point. Gee is not interested, especially about the use of the wine case. Gharty struggles as he tries to reconstruct the events of the night before. Munch is bothered by Gharty's stories of Vietnam and each grows to dislike the other - perhaps some competitiveness over Billie Lou is beginning to brew here. Bounty hunter P.J. Johnson, who was identified as the triggerman, is charged and placed in one of the holding cells, near some of his previously captured quarry. Within an hour his ba

Lewis is transported to the hospital, as is the passenger of the car that MGee hit. Gharty is worked up about women and finances, because he and Flora and their lawyers are going to be working out the financial details of their divorce. Gee & MGee are not interested in cooperating with the bounty hunters; however, Knoll is the only one who can get any information on the whereabouts of Errico from Errico's mother. She has promised to page Knoll when her son calls. (Joe Errico has gone south to Miami.) Knoll offers to pay the expenses of having homicide detectives go to Miami and work with him, but Gee declines that generous offer and sends his detectives separately. In Miami, Bayliss and MGee work with Knoll to capture Errico. Knoll offers to split the huge bounty with the homicide detectives, which they of course refuse. MGee decides that the best use for the bounty might be for the man whose wife had died from the injuries she sustained in the car accident.

When the men are nowhere to be found, Sheppard and Ballard team up to investigate the death of young girl, who's a teenage gang member. With the wedding one week away, Billie Lou asks for Munch's help with her neighbor's abusive boyfriend. After Munch approaches him strongly, the boyfriend retaliates by coming to the Waterfront and slamming Billie Lou's head on the bar. Munch claims he came on strong with the guy, because his ""testosterone riddled behavior"" was due to the celibacy Billie Lou imposed on him, to make their wedding night more special. Billie Lou wants to delay the wedding until the welt on her forehead goes away in about 3 weeks. After Sheppard and Ballard solve their case, Sheppard reminds Lewis that his problem with her is not going to keep her from doing her job.

Kellerman and Lewis (with Brodie) investigate a shooting at the New Moon motel, where everyone there has a motive for the crime. They split up and canvass the denizens of the motel; Lewis also searches for the victim's missing boot. The murder is just one of the many crimes that has occurred or is occurring at this establishment.

A prominent attorney is murdered and the murderer presents himself to Pembleton and Bayliss with a videotape that implicates him. Brodie works on increasing his self-image. Kellerman is determined to find out who's the ""lunch bandit."" The NSA steps in on Pembleton's murder investigation and provides him with a guilty party, even though they know he didn't do it. Bayliss' disgust with the interference doesn't sit well with Gaffney who wants to charge him with insubordination.

Danvers brings news of his appointment to the District Court bench as the investigation of a government official named Janine McBride continues in New York. Their prime suspect Chesley Purcell is dead and her shooter is in the hands of the Feds. The Baltimore detectives investigate the background of Chesley Purcell and it turns up the name of a man in prison who still appears to be running his organization. This crossover starts on Law and Order S09E14 Sideshow (I).

Sheppard and Lewis investigate the death of a man who has a twin brother. Gharty talks about wanting to live his life; he and Ballard go to the hospital to investigate the death of a teenager. Bayliss has interest in Sheppard; later he seeks advice from Stivers, who tells him to get in line behind Lewis and Falsone. Lewis and Sheppard interview the remaining twin and his mother; she confirms his story and they try to point to the dead twin's girlfriend. Meanwhile the friend of the teenage victim in Ballard and Gharty's case confesses that his friend wasn't shot in Baltimore, but rather D.C.; he drove his friend back to Baltimore so their parent's wouldn't ""kill them"" for buying drugs in D.C. Gee hopes to get the case moved to D.C. Mike Giardello puts in for his FBI transfer, but the only openings they have in the area are for liaisons to local police departments. He interviews with Gaffney, who is so open to the idea, he can't wait to tell Gee. That's something Mike was going to wait f

Ballard is annoyed when she finds out that the fact that she had a date with Falsone is around the squad room. Munch has a doctor's appointment and he's not talking about it. Dr. Griscom calls on the homicide unit when he sees a number of deaths that are related by a poison named phosphozine. The FBI steps in on the poisonings and they put MGee in charge of a task force; they consider it an act of domestic terrorism. One of the victims was a priest; two others were his parishioners. Gharty suspects the communion wine. Following this idea, wine bottles are collected from churches around the city. A needle hole is found through one of the corks. A citywide canvassing of all places where wine can be purchased is launched. Gee disagrees with the bureau's policy of keep information from the public. One possible suspect is captured; however, strange as he is, he's not the one. Through an internal leak, the media is alerted and warns the public, sparking chaos. MGee suspects the source of the

Falsone and Lewis investigate the murder of a man in his own backyard. The victim's nose was removed from his body. Ballard and Gharty investigate the murder of a bartender at a strip club. Canvassing the neighbors, Falsone feels that one of the neighbors isn't what she appears to be. Later when they interview her husband, he gets the same feeling.
