When a Turkish worker is stabbed to death in Frankfurt's red light district, Kemal Kayankaya, a Turkish German private investigator, is hired by the murdered man's wife to find his killer. With first-hand experience of the resentment directed against foreigners in his now-native Germany, Kayankaya is plunged into an uncomfortably personal mesh of drug addiction, prostitution and police cover-ups as he nears the truth behind the Turkish worker's death.
