After a bank robbery in the heart of Vienna, the cunning small-time crook Chester takes refuge with the childlike, naive stamp dealer Herbert. A very bad choice, as Herbert destroys all of his prey due to his clumsiness. Chester, with underworld capo Otto breathing down his neck, is devastated. Then he finds out that Herbert’s only relative, Aunt Hertha, has taken out generous life insurance for her nephew and sees his money worries solved. The way there: an adventurous plan.
