A train pulls into Copenhagen Central Station, and 16-year-old Dorte gets off. She needs to find some people on a road somewhere near Svanemøllen. Here, in a beautiful villa, lives Asger Haensen, a director who runs a large company in Copenhagen. He lives with his two children, Margot and Steen. Asger Haensen lives a superficial and overly expensive life—among other things, he has an expensive girlfriend. In the evening, the doorbell rings at the director's house. Outside stands Dorte with a letter that must be delivered to him personally. The letter reveals that Dorte is the result of a small youthful mistake on the part of the director. So Dorte stays in the house. Dorte does not quite fit into the elegant home. But she is feisty—and brings life to the house!
