Knut Hellstein comes to commissioner Krüger's mobile home, demanding help in a dirty game in the energy business, calling a marker from the cop, who accepts unofficially as he failed to d-save Knut's father Karsten Hellstein, who ended up suicidal. Krüger soon suspects Knut being accomplice as well as victim. Krüger ends up comatose due to a fire bomb on his caravan, before he can question the key witness. Beat cop Fichte dragged him out of the flames and continues the investigation, while Krüger has visions including dead people. The case also involves a blackmailer, corruption in privatizing after the reunification of Germany and Knut's ex Jackie and her fatherless baby.
