The parents and Marek help Tomek to paint the apartment. A boy invites his family over for a disgusting dinner and argues with his roommates about the rules in the apartment.
Tomek's been maneuvering so that he doesn't have to worry about food. He drops by to visit his parents, or invites them to his house with some food. Old junk from the grandparents still blocks the garage and the renovation of Kacper's room, although the boys can find interesting things out of it.

At the last minute, Natalia and Ludwik's work prevents them from going on holiday with their children. They are replaced by Marek and Maria. All five go to Grudziadz, to a hotel by the lake.
Natalia is working on a project with her college friends, which results in bending the house rules. Tomek wriggles away from cooking at home and from his job at the sandwich bar. All at the expense of Natalia.
