"This bizarre thriller opens with a violent argument in which a husband is hit with a frying pan by his wife in self defense. His rich father hires a blackmailer, but the latter fails to find any transgressions despite the fact the wife was a nude dancer onetime. He slips her some LSD in an effort to make her lose her mind. The father-in-law and the blackmailer make plans to discredit her reputation, but the scheme backfires on them. Director Claude Chabrol's admiration for the work of Alfred Hitchcock is evident."
