Herve argues with his wife, after which he meets an appealing woman at a nightclub. A subsequent one-night stand with her turns into a tragedy when the woman is killed.

Nightclub entertainer Jean Clery discovers too late that the 'baby' he agreed to take care of is a wild, shapely sex kitten.

This movie is a Marcel Aymé adaptation and it deals with the not-so-glorious side of the Occupation: black market, war profiteers, cracking open bottles of Champagne while most of the Parisians are almost starving.
