Falke investigates a series of car arsons. (Hamburg)

Falke teams up with BKA investigator Julia Grosz on a murder case.

Two shots were fired from Falke's weapon. He and his colleague Grosz come under suspicion and have to face internal investigations. But there are also others who had an interest in the young woman's death. Were Falke and Grosz used and should they now be made scapegoats or has their use actually gotten out of hand?
