Tatort is a long-running German/Austrian/Swiss crime television series set in various parts of these countries. The show is broadcast on the channels of ARD in Germany, ORF in Austria and SF1 in Switzerland.

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.

After getting kicked out of her home, Manou, a young drifter, hitchhikes a ride with troubled sales rep Johannes. Their chance encounter on this hot summer day offers an escape from their struggles but reality soon enters the picture.
