The film opens with Jean-Pierre Armand and a male, presumably Gregory, being entertained by two strippers. One is blonde (XNK0388, but this could be Danièle David with curlier hair) and the other brunette (Sophie Duflot). They strip then dress then have sex with the two men.
Then Gregory looks up the death notices in Le Figaro and the theme of Veuves en chaleur resumes, but with more comedy - very Carry-On style. They disagree on tactics, however. Jean-Pierre thinks a visit is better, Gregory favours a letter of condolence.
The first widow is Brigitte Lahaie. Jean-Pierre visits her and calls her Madame ..., but, tearfully, she says "Appelez-moi Madeleine." So he turns away and shouts "Madeleine!" thinking Madeleine is the maid. This gives her the giggles and leads to a b/g scene.
