At the beginning of the film, gangster Bruno Stiegler alias Dandy returns to West Berlin from the United States as a boxing promoter.

The now retired Judge Zänker has tried in vain to put Dandy behind bars by legal means during his active service.

Dandy wants to steal the revenue from a Hertha BSC football match at the Olympic Stadium, but Zänker and his gang are faster in doing so.

The same is achieved by them with Dandy's attempt to rob dubious businessman Kunkelmann's cash cabinet and clean out the Haase jewellery store during a parade.
