When a Turkish laborer is stabbed to death in Frankfurt's red light district, the local polcie see no need to work overtime. But when the laborer's wife comes to him for help, wise-cracking detective Kemal Kayankaya, a Turkish immigrant himself, smells a rat. The dead man wasn't the kind of guy who spent time with prostitutes. What gives? The deeper he digs, the more Kayankaya finds that the vitim was a good guy, a poor immigrant just trying to look out for his family. So who wanted him dead, and why? On the way to find out, Kayankaya has run-ins with prostitutes and drug addicts, gets beaten up by anonymous thugs, survives a gas attack, and suffers several close encounters with a Fiat.
