Vogler and Hagerman fight a group of prostitutes who are knocking off gangsters and inflaming tensions in the underworld. Racken and Tannhäuser, convinced that each other are behind the attacks, declare war, threatening to destroy the entire city.

A teenager goes on a violent rampage and kills several people, impressing Vogler. Vogler encourages the boy to embrace his dark side, but Vogler then must defuse a hostage situation at the school when it turns out that a new drug is the cause of the violence in the city. Vogler is shot in the face again during the hostage crisis, which drives him even further into madness.

Vogler and Hagerman investigate a series of apparent suicides by priests, uncovering a conspiracy involving a dentist-hitman and gangsters who are hiding out in churches.

Everyone converges on the hospital in which Martine is giving birth. Martine reveals that she's been playing all sides against each other so that she can take control of the underworld. Her pregnancy is revealed to have been a ruse, and she pulls out a submachine gun from the prosthetic belly, killing Racken and his men. While Martine prepares to kill Vogler once again, a bomb planted by Tannhäuser's men counts down to zero. The show fades to black on that cliffhanger.

Gunter Vogler, a vicious criminal, is betrayed and left for dead, only to be recruited by the police, who want to use him against the mob. Given a badge and authority, Vogler becomes even more dangerous and out of control.

Vogler confronts Racken, exposes some dirty cops, and attempts to figure out Martine's plans. Martine has convinced Tannhäuser, Racken, and Vogler that each man is the father of her baby, and has even married Racken while living under a false identity. More curious than anything else, Vogler does not expose Martine to Racken.
