The Dortmund homicide team has no time to properly greet their new boss at the police headquarters: they experience Peter Faber and his idiosyncratic investigative methods directly at the scene of the crime. The student Kai Schiplok (Tom Viehoefer) was found dead in his apartment , naked and only covered with a cloth. The first traces point to a jealousy drama. The murder victim was known for his easy-going lifestyle. His ex-boyfriend Lars Bremer (Christoph Jöde) obviously suffered from this.
