Romy Schneider plays an aristocratic woman in 1936 Greece, who amuses herself pursuing a shallow loveless affair with a nobleman, but unexpectedly falls in love with a political activist.
On August 4, 1936, General Metaxas declared martial law in Greece. A union leader using the name Boutros is sought in Athens by Primoukis, a ruthless police leader. Boutros narrowly escapes and, early the next morning, jumps through the window of Marchese Margot Santorini, the wealthy Austrian-born wife of Rico, a penniless Italian diplomat and playboy. Margot is bored and without purpose: aiding Boutros's escape invigorates her, and soon she is in love. The film briefly jumps to 1945 when Rico and Raoul (who assisted her out of love) meet in France to talk about her fate, and then jumps 30 years to Margot's daughter's visit to Greece to find out about her father.

Having fortuitously discovered a photograph in which Marthe embraces someone unknown, clothed with a chequed jacket, Étienne Dorsay becomes jealous, and imagines various stratagems to identify the lover.
In the meantime, Étienne and his friends acquire a weekend house for a very low price.
As in the previous work, the film is largely narrated by the character Étienne, whose tone shifts with the reality of the images.
The film contains a certain number of allusions to the films of Blake Edwards (the Pink Panther series).
