In extremis (1987)

A brash young man decides he’ll do anything to woo a sultry brunette--even if it means impersonating a dangerous criminal--in the erotic French drama In extremis (1987). Small-time hustler Tango (Philippe Caroit) is so smitten with sexy Alice (Sophie Duez) that he adopts the persona of a violent hooligan named Rock (Julien Maurel) to impress her. In fact, the biggest impression Tango makes is on Rock himself, who’s none too happy about the identity swap. Poor Alice is caught in the middle, which is mostly fine, because there’s plenty of the curvy beauty to go around. Duez shows off every angle of her impressive bod in a series of skinny-dipping, shower, and kinky sex scenes.
