Winterherz: Tod in einer kalten Nacht.

After a night out at a disco, 17-year-old Finn is hit by a car driven by aspiring judge Maxim Vollert. He leaves the seemingly uninjured man behind, who succumbs to his internal injuries. Finn's brother Mike, who reproaches himself for letting the drunk Finn walk home alone, meets Sylvie Vollert at Finn's grave, who was sitting next to her husband in the car on the night of the accident. A passionate relationship develops between Mike and Sylvie. Mike soon suspects that Sylvie was involved in his brother's death. When Mike tells his parents about the growing suspicions against the Vollerts and his mother finds out about the liaison between Mike and Sylvie, her world collapses.
