Carolin and Moritz Seitz were once known as a successful couple of actors. But today she is considered the wife of a murderer: Four years ago, Moritz Seitz was convicted of killing the former theater star Thore Bärwald after an excessive New Year's Eve party. Now Ole Stark turns himself in to the police. He is also an actor and claims to be the real killer. The public prosecutor's office cannot initiate new investigations, but they give the Cologne inspectors Ballauf and Schenk a week to find out what is true of the story that is being served up to them.
