Unscrupulous boxing promoters, violent bookmakers, a Russian gangster, incompetent amateur robbers and supposedly Jewish jewelers fight to track down a priceless stolen diamond.

In this classic German thriller, Hans Beckert, a serial killer who preys on children, becomes the focus of a massive Berlin police manhunt. Beckert's heinous crimes are so repellant and disruptive to city life that he is even targeted by others in the seedy underworld network. With both cops and criminals in pursuit, the murderer soon realizes that people are on his trail, sending him into a tense, panicked attempt to escape justice.

Injustice and the demands of the world can cause stress for many people. Some of them, however, explode. This includes a waitress serving a grouchy loan shark, an altercation between two motorists, an ill-fated wedding reception, and a wealthy businessman who tries to buy his family out of trouble.
