The boy and another alien in a doctor's body are trying to extract chemicals for Zin. The Odulian, an aquatic creature, dodges their first attempt to capture him by taking refuge in Lake Michigan. Cole determines the alien needs certain elements to survive, and normal lake water won't suffice because of its high zinc content.

A young girl, Jamie Swenson, miraculously recovers from an illness and subsequently heals an electrocuted boy. This catches the attention of Cole, who investigates. Jamie has been taken over by Lontoria, a Cyrrhonian prisoner (of the same race as Cole). who escaped from Satrap.

Zin (passing as a movie producer) wants her to use her powers for his own ends, and the local sheriff is another of the escaped prisoners. Cole is conflicted because he and Lontoria were friends. Meanwhile, the local priest, Father Creighton, believes that ""Jamie's"" powers are God-given, and tries to give her refuge in a church.

Suspects abound, but Cole manages to track them down, only to be knocked out and find out the whole thing was a set up so that the two convicts could get into the Watchfire Bar and release Cole's imprisoned lifeforce/aliens. With Mel's help Cole manages to escape and thwart the two just before they can succeed. The two resolve that they can't be distracted by romance again.

Cole gets hold of a tape made at the train station when the passengers from the alien-intercepted train arrives. He identifies one of them as Yahir, an aide of Zin's who may have vital knowledge of Zin's plans and the metal triangle Mel's grandmother has. Yahir's body was that of Rudy, a mental patient who has since been taken back to the asylum. Cole poses as a mental patient to reach Rudy and cuts off his dosage so that he can be interrogated about Zin's master plan. Things go amiss when Rudy/Yahir gains his memories back, drugs Cole, and tries to escape with Mel. Cole manages to escape with the aid of his fellow patients, and stops Yahir just in time, capturing his lifeforce before he can gain any information except that the triangle is a key of some sort, capable of letting the prisoners return home.

Cole interrupts a mob transaction between Jimmy and one of the prisoners, Trepp. Cole captures Trepp and escapes, but realizes that Zin and the mob are connected somehow.

Zin and Tommy's gang are rivals, with Zin taking over their territory. Despite Jimmy's suspicions and Vic's interference, Cole manages to find out that Zin is drilling 300' down in several buildings in the downtown area.

He defeats Jager but alerts Parker, his twin-Orsian. Suudor tries to kill Mel and Cole catches up to him but is flash-frozen by Parker. It was a trap to lure Cole in. Suudor goes to kill Mel but Cole manges to recover enough to freeze time, rescue her, capture Suudor, and escape.

The U.S. government project devoted to detecting aliens (from ""Breach"") is back in action. They are keeping the body of Wes Tarber, previously inhabited by the Nodulian Kres alive, and bring Zan (disguised as a ""Dr. Armstrong"") in to revive him. Zan succeeds by injecting it with the essence of Ramel, who didn't get a body in the original takeover because there weren't enough humans on the train. Zin needs access to files in the complex and revives Ramel to get in good, but kills the general he's bribing when the general gets antsy. Meanwhile Cole is analyzing Mel's grandmother's key, which apparently opens some kind of ""door"" beneath the Watchfire. Ramel attacks Cole, who killed his brother previously, but Cole escapes. Cole sneaks into the complex, and finds out that a Vardian ship piloted by an ""Arkin"" crashed into Lake Michigan. A ""Dr. Milos Sandborn"" interrogated the alien and then disappeared before giving his files to the government. Zin wants the files and needs Ramel to help se

Nestov warns Cole that Zin has created a gun that permanently nullifes Cirronian energies, turning them into normal humans for good. The two break into one of Zin's bases and steal it...only for Nestov to turn around and shoot Cole with it!

She ""jump starts"" him back into his energized state, while Zin unearths the vault beneath the Watchfire and goes down into it. Mel and Cole defeat Zin's henchmen (with Mel using the Collector on one of them!). Nestov reveals he was actually planning a triple-cross, and was hoping Zin would leave. Unfortunately, Cole determines the Vardian device is a universal-destructor unit that Zin plans to use to gain absolute power

After bringing in another escapee after some tests, Cole determines a way to zap all of the remaining prisoners off Earth and back to Sartop at the same time by remote. However, one of the currently held lifeforces is contaminating the process, and he and Mel desperately try to determine which one before the wormhole closes. Things get complicated when Cole is zapped by an energy burst and loses his memory. He gets it back with some prodding from Mel, and they identify the ""contaminated"" lifeforce just in time and get rid of every remaining prisoner on Earth. Cole goes back, his mission completed. But then he returns, realizing his home is on Earth with Mel. But as they celebrate, we see the display screen show all the fugitive prisoners reappearing all over the U.S.
