An accordionist playing in disreputable halls is mistaken for a gangster by a special envoy from the American crime syndicate in charge of investigating the French milieu. The American will prepare a hold-up with a gang of women specialized in scamming tourists. But the accordionist will make the hold-up fail and all the criminals will end up behind bars.
