Since his wife died ten years ago, Karl has been raising his daughter Nic alone. This has left its mark on the 13-year-old schoolgirl: Nic stands out from the girls her age with her short haircut and tomboyish style of dress. In her ice hockey team, which Karl coaches, she easily outplays her male teammates with the odd body check. But everything changes when editor-in-chief Sonja moves in next door and Karl unceremoniously turns the two apartments into a shared flat following an accident. Sonja observes the father-daughter relationship between Karl and Nic and interferes in their upbringing, especially when she realizes that Nic would also like to be a woman and that not everything revolves around ice hockey.
