After putting away the head of the Albanian mafia in Hamburg, Homicide Detectives Thomas Ritter and Motz Beck are confronted with a bloody war to control the local drug trade in the mobster's absence. First an Albanian courier is shotgunned to death at the edge of Hamburg Harbor. Then a Hells Angel gets the same treatment on the Alster River. As the bodies pile up, Ritter and Beck are forced to work with an organized crime expert, a burned-out narcotics agent with his own drug issues. Before long, they suspect that their new partner is working for one of the rival gangs.
