Bára and Venca are getting married, but an unexpected obstacle stands in their way. How could this have happened? Can such a surprising situation be resolved quickly? Will Svatava finally marry them? Bára's uncle Adolf sees it rather negatively - and Johana, the eldest daughter of the parish priest Svatava and the carpenter Pepa, is not thrilled about it either. The Kopalov and Boček families, Venca and Bára's parents, will enjoy the wedding very much. Venca, on the other hand, wishes that today had never happened at all.

Something is wrong here: newlywed Venca didn't sleep at Bára's. Johana vaguely warns her mother Svatava that a lot of trouble is coming, but Svatava interprets it her way - who told Johana about her wild partying from her youth? Svatava first suspects Hynek Kopal, then she herself reveals to Johana her old adventures at the university dormitory. Johana doesn't like to hear about them; only Pepa is sure that it won't be the end of the world.

Venca seems to be coping with the new situation much worse, while Bára, with the help of Adolf and Vladimír, is determined to get to the bottom of things. In the editorial office, Lucka pulls out of Pipi that Venca is living in the editorial office instead of with the Bočeks because Bára wants nothing to do with him. Gossip spreads, the Bočeks are more than confused. Johana thinks it will get worse and that no stone will be left unturned. All they can do is keep their cool and hope that nothing will get as hot as it boils.

Bára and Venca gain an unpleasant certainty and must solve the problem. Monika believes that a woman's skirt will cover everything, but when she reads Bára's girlish diary, she suddenly has a lot of questions and has to come out with the truth herself. Her husband Bob, although he still has no idea, starts filming short videos on social media to bring some order to the confusion. Venca also stops by his parents' bookstore and asks for an explanation of how he came into the world. Only Franta Košťál, grandma's friend, finally has the peace he deserves.

Bára stops by Svatava's place of worship because she already knows the ancient secret of her origin and thinks that Svatava could explain a lot to her. But Svatava can't give her a satisfactory answer. Venca tries to date Káča to forget Bára, but his efforts haven't had much success yet. Grandpa Nekuda won't let anyone help him, everyone is confused, and Tereza getting drunk in a bistro instead of cleaning suddenly doesn't seem like the worst news. And who on earth is František?

It's all a bit too much for carpenter Pepa: he learns from Svatava that Johana's siblings are also Bára and Vencea, and they're calling from the hospital that his father, Grandpa Nekuda, has broken his neck. Monika also rushes into the raging mill with her little one when she only reveals the more bearable half of the truth to Bob: the young people are going to get divorced. But it all ends with a conciliatory Night of Churches, when the newly formed sibling sextet performs a beautiful concert with Eva Olmerová's gospel song, "Ó boží den".

Can you remember all your past partners? Who have you ever dated and how it ended? To help Dáša remember, Hynek makes her a list of potential lovers and sticks it on the fridge, but he certainly doesn't stand up for family peace... Hynek Kopal investigates the world of infidelity. The statistics, in which men are the main unfaithful, definitely don't sit well with him, so he decides to uncover the truth in the family. Klára and her classmates discover that Luděk doesn't have the money to go to an adaptation course with them, and they decide not to let it go. Johana tries to find out more about her sibling in prison.

Dáša Kopalová has another argument with her husband Hynek and sees no other solution than to take a break from him for a while. She finds a suitable refuge with her friend Linda, who is enjoying a well-deserved change in lifestyle. But even yoga and herbs cannot bring Dáša back from the past to the present moment. Waldemar, an experienced psychiatrist who knows that issues of memory and consciousness are usually more complex than they seem at first glance, offers Dáša the opportunity to meet with an expert. Svatava decides to join Johana's investigation and go to prison to find out more about her other sibling.

Svatava gets permission to stand in for the prison. She goes to the Teplice prison to say mass, and on that occasion she would like to talk to František. Johana is rather lukewarm about it, she doesn't want to know more than is absolutely necessary. But she realizes that she shouldn't keep secrets from Bára and Venca. Hynek admits to Venca that there are a couple of angry husbands who could ring their doorbell. But Venca is surprised not only by Hynek, but also by the orderly Dáša. And everyone is surprised by the truth about Bára's conception...

Bob and Hynek go to Pepa's workshop to find out who the father of all three children is. But their meeting ends in an argument. Dáša is increasingly angry with Hynek, who wants to get a "lejstro" (a form of proof) that he is not the father. Her anger is directed at poor Bob, who regrets ever coming across her. Pepa is not happy either that memories are materializing again that he would like to banish from his mind once and for all. His "saint" Svatava would accept the large family right away. Her wish is immediately fulfilled in the form of the stubborn grandfather Nekuda, whom she releases from the hospital to home care. Svatava also finds out disturbing things about František's father. And Venca finds a very special way to replace his beloved Bára, who he still misses...

The search for the three cuckolds drags on and Pep is being hunted down at the rectory. He is mainly asked about by a quirky grandfather who is fed up with the careful care of Svatava and the girls and would like to go back home to his cottage. Klára surprises everyone by saying that she is going on a threesome date - all that is missing is for his other two protagonists, Luděk and Michal, to be okay with it. The unexpected almost-date also catches Bára off guard, even more so when an angry and drunk Venca enters the fray quite forcefully. He decides to take his Bára on a romantic trip, right away, regardless of the amount of alcohol he has consumed. But being drunk behind the wheel is not only not responsible, but also not safe...

The irresponsible driving of the drunken and desperate Venec has serious consequences. Fears are not only rampant among Venec's still-legal wife Bára, but also his mother Dáša, who blames Bára for everything. The agitated emotions on all sides are unexpectedly calmed by Monika, except for the rational grandmother, in a way that is unique to her... Klára, as an accomplice in her grandfather's escape, is given the task of checking on him at the cottage. But she wouldn't be unconventional Klára if she hadn't invited both boys − Luďek and Michal − to a sleepover in the wilderness...

Hynek wants everything to be the way it was before. His marriage to Dáša is falling apart and he almost lost the son he loves, even though he is not his own. That is why he promises Venec that he will not continue searching for his biological father. But Bob and Pepa do not want to give up the search. Hynek succumbs to their pressure and at a meeting with other participants of a party at the university dormitory, where Svatava has changed, he finds out something very important...

Tension and distrust between Pepa, Bob and Hynek rise. In the end, the three cuckolds agree to paternity tests. This provokes more than a few violent reactions from the female staff of all the families - except perhaps Grandma Naděžda, who immediately takes the initiative. Bára, who, with the help of Romeš and Svatava, tries to relieve the dying Mrs. Musilová, comes up against her uncompromising superior.

Naděžda energetically takes on the important task of testing Bob, Hynek and Pepa. Pepa is unusually reserved towards Svatava, she is still processing new information that Hynek brought from Prague. The vicarage is unusually busy − the impulsive Bety has arrived home with a new boyfriend, who surprises not only her grandfather. Bety senses that something is different at home. At dinner together, she hits on Svatava and she has to come out with the truth... Bob must also admit the truth, as he was frightened by his brother Adolf with the information that thanks to the paternity tests, one of his left-handed children could easily appear.

The girls at the rectory notice that Marie is rushing to get an assignment for the editorial office. It turns out that it is because of the charming marketeer Lucie, with whom Marie arranges a meeting. Grandpa is also planning a date, but he is unpleasantly surprised by his unexpected rival. The Kopalovs are surprised by Venc, who decides to go on a reverse trip from the hospital and not return home to his parents. Johana, Bety, Klára and Marie want their mom and dad to finally tell each other everything, and in the end, Pepa will be the most surprised, as he refused to celebrate his sixtieth birthday.

Naděžda is faced with a difficult task - her friend Hanka died against her will in the hospital. Now her grandmother is trying to say goodbye to her with dignity. However, Monika has other worries: she suspects her mother-in-law that she has found a suitor, and she begins to worry that this could endanger the family property. Pepa does not want to let Svatava's silence go to her and decides that he will have his secret too. The suffocation between her parents does not escape Maria either - she is also taking Lucie's behavior very hard. But the biggest shock for everyone is caused by the orderly Johana, who is hiding financial problems that can affect the entire family. How will she deal with them and who will unexpectedly offer her help in the end?

Adolf helps Johana out of an impending mess. It is impossible not to notice that something is brewing between the two. But everything comes to a head when Adolf's unwelcome initiative, which he wants to impress Johana, comes to an end. How will Johana understand his gesture? In addition to these two, Hynek unexpectedly gets along with Dr. Hánová. What will be the reaction of Dáša, who will not miss any opportunity to poke fun at Hynek? Tereza and Luďek have completely different worries. They are troubled by a constant lack of money, but proud Tereza refuses to ask for help from her father, the well-off Roman Sojka, who constantly comes up to her and trips her up.

The promising relationship between Johana and Adolf is starting to get a bit complicated. In addition, Bety, who is a bit bored with Hung, also shows interest in Adolf. What will Adolf do to convince Johana that there is more to their relationship than just a debtor and creditor relationship? Things are also complicated between Maria and Lucka, who are trying to push Venc towards each other. For him, this is at least a small positive plus in a situation where the trial for a drunken car accident is approaching. Bob is the most tense, however. He can't wait for the results of the paternity test to appear in the database. When he finally finds them there, his joy knows no bounds. But will everyone be as excited as he is?

Venca is worried about the upcoming trial, especially when he finds out what punishment he faces. Hynek, who paid for Venca's damage to Bob's car, brings light to the gloom. Dáša feels that Hynek is buying Venca to win him over to his side. She has no idea who Hynek meets with in the pub in the evenings. Relationship problems will not leave alone not only Maria, who is in love, but also Klára, who is trying to establish her unconventional relationship with Luďek and Michal. Bob intervenes in the situation with his advice. Will they fall on fertile ground with Michal?

A quirky young man comes to the bistro asking about Johana. Káča immediately realizes that Johana has a stalker on her tail. But the truth is completely different: it's Johana's, Venců's and Bára's brother Kamil. How will the siblings accept his arrival? And what does Kamil want from them? Meanwhile, Monika and Dáša decide to take the next step: they want to hear the truth about their fertilization from the most qualified person - their former gynecologist Sojka. Sojka decides to tell them the truth. Dáša is in for a shocking revelation that will also affect Hynek. And then the results of Pepo's test come into play. Will they finally bring answers, or just more questions for the "three cuckolds"?

Dáša does not want to accept that the truth about Venc's conception remains unspoken, and sharply confronts Roman Sojka. A real uproar occurs at the Sojka family table. His son Martin, who has taken over his father's gynecological practice and needs to know if it was just a one-off incident, is the most affected. Sojka defends himself and swears that it was a one-off incident. But Dáša is not satisfied with his explanation, and he and Monika agree to continue investigating...

Bára and Vencea are planning a divorce party, which is turning from an initially intimate event into something bigger. Will the "Reverse Wedding" help them close one chapter, or will it rather open up new questions? And is it even possible that the truth about the siblings in small Bydžov will not come out sooner or later? Meanwhile, Monika and Dáša meet Svatava, who, after thirty years, finally reveals how it really was back then - but at the same time asks them not to tell anyone. Monika feels like she is going to explode, and Bob is also in a difficult situation - but for something completely different. As a man from the "old school", he tries to figure out how Klára and his Michal are really doing when she kisses Luďek in front of him...

Monika is convinced that Bára is suffering because of Venec and the divorce. But Bára admits that something else is gnawing at her – she doesn't know whose genes are part of her. Monika can't help her with that anymore. At work, old Mr. Verner brings a smile to Bára's face when he declares that he is her father. If only it were that easy! Bára is determined to go see Roman Sojka, despite Johana's warning that every new piece of information means more trouble. Her daughter's suffering also affects Bob, who finds today's world increasingly complicated – and he is not only referring to artificial insemination, but also to the incomprehensible relationship between Michal, Klára and Luďek, which is collapsing under the weight of their naive ideas...

Bára is determined to find out who her biological father is. In front of witnesses, she confronts Roman Sojka, who insists that donation is anonymous in our country and there are no records. However, Bára does not give up - she reminds him that in detective stories the perpetrator is always found thanks to DNA, and she does have one half of the DNA. She also involves her grandmother in the search, while Sojka faces the growing restlessness of his wife Helena at home. Do the Sojkas know more than they have been willing to admit? Meanwhile, Venca tries to win over Káča, who is cautious after her previous experience and goes to Bára for her blessing. Kopal wants a relationship for his son, but he does not want him to fall into something similar to what he is currently experiencing with his wife Dáša. Does Vencia and Káča's love have a chance?

Kamil moves to Bydžov and buys his own apartment to be closer to his siblings. Venc is suspicious, however – especially when he gets only an evasive answer when asked what he does for a living. Isn't Kamil running away from something? His mother Marta will soon arrive in Bydžov, and she is surprised by her son's sudden decision. Bára and Johana want to get her to confess who Kamil's and therefore their father is. Marta admits that she knows him, but she once promised him that she wouldn't reveal his name. Kamil confirms her words – he hasn't gotten anything out of her for years. But Bára doesn't give up and keeps coming after Marta. What will Marta eventually reveal – and will the siblings at least get a clue to the truth?

Marie suspects that Svatava is hiding something from the family - and this time she decides not to back down. She makes her mother finally face the truth that she has been hiding for so many years... Meanwhile, the Kopals try to save their marriage in couples therapy, but things don't go as planned there either. Bety comes back into the mix - with a new love and a big surprise.

Hynek is on a journey to find his old self, but Dáš doesn't like his methods at all - at least the fact that he's having a spermogram done. However, the Sojkas are dealing with much more serious problems. A rumor is spreading in Bydžov that could harm not only Roman Sojka, but especially his son Martin.

Monika Bočková is known to be a gossip. But some gossip can be dangerous. While Monika tries to stop the havoc she has caused, Bety is dealing with something that no woman wants to deal with - especially not while pregnant. She would like to deal with it herself, but the family keeps asking the same question: When will Richard arrive? And then there's Hynek Kopal, who discovered that his sperm are completely functional. So he and Dáša were cheated on. And Hynek won't keep that to himself.

Bety is happy about her pregnancy, but in the family it turns into an endless interrogation. Johana remains her support, who in the meantime is increasingly developing her relationship with Adolf Boček - but Pepa does not like this at all. How will Adolf's confrontation with Pepa turn out regarding the debt that Adolf paid for Johana? Kopal is faced with the decision of whether to publish his article about how Sojka once tripped them up. Míra gives him space in Koloběh, but Roman Sojka also has something to say about it. Will it be a word against a word?

Kopal's article about medical manipulation is published in a completely different form than the one he wrote. Sojka tries to turn the situation to her advantage, while Venca in the editorial office finds out who is behind the rewriting of the article and why. Bety goes to Richard to finally find out what they are up to. However, instead of a warm welcome, she is met with a cruel truth. Kamil invites his siblings to his new apartment to reunite the family. Will he be able to convince them that it is easier to seek the truth together than each of them separately?

Kopal's article reappears on the website - this time without censorship. Sojka tries to extinguish the scandal, Waldemar is ashamed of his son and the mayor is furious. Meanwhile, one decision after another is made in the editorial office and it seems that Koloběh can no longer save anything. But Lucie comes up with an unexpected plan, while Bety discovers that she is really pregnant. And the members of the "Funeral Brotherhood" - Waldemar, Anežka, Naděžda and Ruda - embark on an event called Previously Expressed Wishes.

Serious situations force us to make difficult decisions. Vencu is facing trial, Hynek is considering Sojka's offer, and Bára is wondering if it wouldn't be better to come out with the truth. Meanwhile, Bety is experiencing a dilemma regarding her pregnancy. Who among them will make the right choice? And is there even such a thing as the right choice?
