Gentlemen in White Vests

At the beginning of the film, gangster Bruno Stiegler alias Dandy returns to West Berlin from the United States as a boxing promoter. The boxing business serves him more as a camouflage, however, because soon it turns out that he and his gang want to realize various planned raids. The now retired Judge Zänker has tried in vain to put Dandy behind bars by legal means during his active service. Now he turns the tables with his friends and sister Elisabeth. His old friends and colleagues meet as a men's choir disguised in his home and prove to be a pensioner's gang, taking on Dandy's gang. He succeeds in this by using the ex-con Pietsch as a snitch in Dandy's gang.
