Tom and Semir are distracted by a murder case in a motorway car park after leaving Meike Moritz, a woman who has broken down, behind. Shortly after they help her, Meike is found murdered. Tom is plagued by guilt and throws himself into the investigation. The suspects - Meike's husband Frank, the breakdown helper Rolf Pfeifer and the designer Robin Jakoby - all have an alibi. Meanwhile, another victim is found, Sabine Grauberg, and it is suggested that a psychopath who cuts the victims' hair is behind the murders. (thetvdb.com)
