Commercial director Serge Faberge is having an affair with Evelyne, the 18 year old fiancee of friend Hugh. His own pregnant wife Francoise usually does not mind his dalliances, until he actually walks out on her and their newborn baby to move in with Evelyne. The shoe is on the other foot when dashing stuntman Dado catches Evelyne's eye in Venice.
