Perkins tries to convince his friend Ronet to sell his interest in a champagne company, but Ronet refuses. The women Ronet sleeps with start turning up dead in the morning, and eventually it is revealed that Audran, secretary to Perkins' wife, has been committing the murders so that
Perkins can take over his wife's fortune. Alfred Hitchcock's influence on Chabrol is evident in every frame of this film, but THE CHAMPAGNE MURDERS is an infuriatingly elliptical movie, ending in the middle of a struggle for the gun wielded by Audran. Shot simultaneously in French and English.
