Murder and robbery in Munich local transport - for Vera Lanz and her colleagues Trompeter and Böhmer it seems to be an uncomplicated case. Using a video recording, Böhmer can clearly identify the fugitive. But when the colleagues visit his apartment, the dimension of the case suddenly changes. Till Sammer, ex-pimp and junkie sits tied up in his own apartment, threatened by a stranger. In a dramatic exchange of fire, Trompeter shoots the man in self-defense. The victim's car is registered to an old friend: Stefan Hartig. For years, Vera Lanz has been trying to prove that the slippery businessman is doing his shady business - so far without success. The stolen briefcase has another surprise in store: two million in cash. Vera Lanz confronts Stefan Hartig about the money.
Is he being blackmailed? The investigators quickly agree that it must be a kidnapping and that Till Sammer prevented the money from being handed over. But who is the abductee? Hartig's only relative, his luxury son Jakob, is hungover but safe in his penthouse apartment. But Jakob gives the key clue as to who the kidnapping victim is: Johanna Ehrlicher, housekeeper and Stefan Hartig's closest confidante since childhood. To the astonishment of her colleagues, Vera decides to cooperate with Hartig: he gets the money that was secured for the kidnappers, while Vera hopes the housekeeper will give her the crucial information she needs to finally pin Hartig down.
