Míša comes to Prague to start a new life. Her friend and ex-boyfriend Marek promised her that he would arrange accommodation for her, but when she arrives at the place, she discovers that things will not be so simple. Marek lives in an apartment with five other roommates.

Tension is building in the apartment. Leyla considers Míša to be a direct competitor in the fight for Marko's heart. Olda falls in love with an unknown girl and believes that luck has finally smiled on him, while Joe fights for his daughter Hanka with his ex-girlfriend Klára.

Marek gets a chance to show his talent for photography, because he is hired to photograph a private fashion show. Joe slowly discovers that his "innocent daughter" is no longer a little girl. Leyla senses that she is losing the battle for Marko's heart, and she also feels that Míša is winning her best friend Aňa over to her side.

Hanka introduces Joe to his friend Krtek, who doesn't like him at all. On the other hand, he is glad that Hanka let him into her life. Marek completes his first big photo shoot and reaps success. Sofi, who falls in love with barman and well-known womanizer Karlos, also has a big day.

Thanks to Franta, Olda manages to pay off his rent debt and can stay in the apartment. However, when he allows Hanka to drink alcohol at the party in the evening, Joe gets angry and wants to throw him out of the apartment again. Marek will experience one of the worst days in his life. He discovers that the big photo shoot was just an excuse for Natalia to get him into bed. Joe spends the night with confident Petra, but she refuses to let it be a one-off affair.

Bořek, Míša's ex-boyfriend, who made her run away from Ostrava, will visit Prague. He persistently demands a meeting with her - and Míša knows that he will stop at nothing in his quest to take her back home. Meanwhile, Olda has to move out of the apartment. Joe takes pity on him only at the last minute. He has enough problems of his own – he can't get rid of Petra, who has simply decided that a one-night stand is not enough for her.

Bořek does not give up and threatens to throw Míša out of the theater because of him. Aňa invites the masseuse Kamila on a date, but she is beginning to be bothered by Aňa's bisexual orientation. While the others deal with their complicated relationships, Olda decides to learn from Franta how to pack girls properly.

The roommates are surprised by the arrival of Franta's family. Despite her common sense, Sofi resumes her relationship with Karlos and a physical fight takes place between Borek and Marek, when Marek pretends to be Misa's new boyfriend.

An unexpected meeting with a former friend from Brno brings back painful memories for Leyla. Sofi is excited about her relationship with Karlos, but when she hears some gossip about him from her ex-girlfriend, she hesitates again. During the day, Míša takes care of Marko, who was wounded in a heroic fight when he defended her from Bořek. Their mutual closeness turns into sex, which threatens their entire friendship.

The relationship between Sofi and Karlos is like an endless story. Not even the other girls can talk him out of it, and it even goes so far as to move him into an apartment. Joe makes one more attempt to end his relationship with Petra. And when Leyla learns that Marek and Míša slept together, she collapses.

The news spreads in the apartment that Míša and Marek slept together. Leyla is devastated and is considering returning to Brno. Franta is depressed because his wife sent him his things. And Joe attends his daughter's birthday party, which doesn't turn out the way he expected.

Joe finally finds his way to Hank, but she misinterprets his words and decides to move out of the house. Party animal Julie - Mark's sister, who came to steam and have fun - will also stir up the waters in Prague. Meanwhile, Fran's secrets begin to spiral out of control, threatening his friendship with Joe.

Franta is desperately fighting on two fronts - trying to repair his relationship with Joe and his wife. Marek tries desperately to get his sister under control, but she has no interest in anything but alcohol, parties and boys. When she finally ends up in the shower with Karlos, there is a threat that the whole apartment will fight over her.

Julie is unstoppable and Marek can't stand her anymore. She asks Míša to talk to her, but Julie is not interested. Franta is fighting for his wife Irena and in desperation calls Olda for help. When Irena finally decides to forgive him, she has a condition - he must return to Česká Lípa with her. A devastated Marek spends the evening with Míša, and when memories overwhelm them, they end up in bed together.

With Olda's help, Franta manages to win Irena back and leaves with her to her hometown. Meanwhile, Marek and Míša start a secret relationship, because Míša is afraid that disclosure could lead to unnecessary arguments. The cup of patience with Julia overflows and Marek eventually throws her out of the apartment.
