Lohmann Solar Technology GmbH is about to go bankrupt. In desperation, Hajo Lohmann (Peter Trabner) and his wife Biggi (Katharina Marie Schubert) attempt insurance fraud and stage a robbery. However, when they are surprised by a security man, Biggi grabs his gun and shoots the man with a well-aimed shot between the eyes.
Brix and Janneke are faced with a riddle: Who is stealing from a small, medium-sized company? Are they professionals at work here? And which master marksman was responsible for the murder of the security man?

When the would-be gangsters then also come into contact with real gangsters, they all try to cheat each other without anyone really keeping track.
When Biggi's insurance company refuses to pay, she desperately tries to save what can be saved - and slowly but surely sinks into her self-inflicted misery...
