A woman (later revealed to be a transvestite), dancing provocatively to the enjoyment of other nightclub patrons, is abruptly hit in the face by Hubert Florentini (Reno), a commisaire of the French Police. Florentini drags her out of the club in handcuffs, assaulting other patrons who come too close to free the captive woman or attempt to hinder his exit. Unfortunately, one of these patrons includes the chief's son.
