When Homicide Detective Thomas Ritter transfers to Hamburg, he has no idea he has stepped into the biggest police scandal in the city's history. No one told Ritter that his new partner, Motz Beck, is a moody biker with family ties to local mob boss Willi Kaiser, who controls the red-light district. Or that Kaiser is fighting a hostile takeover from the head of the Albanian mafia, the silent real estate partner of a prominent senator. After Hamburg's top cop is found dead in a Kaiser whorehouse, Ritter and Beck conclude that the only people they trust less than each other are their bosses in City Hall.
