Maria doesn't like her mother's new boyfriend Robert. He has his own daughter, Lisa.

Bosse works at an advertising agency while working on the novel of the century. At a burger restaurant he meets Lena, and before he knows it, she is pregnant. Bosse starts thinking that his life is all over, he won't get any more career opportunities, and never again will he have time for late night parties.

Nine people - three couples, one unmarried mother and two children - try to change and improve their lives by forming big families. Eva feels oppressed by her conventional parents. Vera and Lasse live with their daughter in a depressing suburb environment. Lena lives alone with her three-year-old son Pelle. Sven and Bibi live together in a small one-room apartment where they constantly quarrel. Sven sees the big family most as an opportunity for sexual experiments. A young French medical student, Paul, meets Bibi through common acquaintances and moves into the collective. The reason is simply that he has been attracted to Bibi. Meanwhile, Sven is increasingly interested in Lena.
