The light touch of the masters! Malle makes… Belmondo takes.

In turn-of-the-century Paris, Georges Randal is brought up by his wealthy uncle, who steals his inheritance. Georges hopes to marry his cousin Charlotte, but his uncle arranges for her to marry a rich neighbour. In retaliation, Georges steals the fiancé's family jewels, and enjoys the experience so much that he embarks upon a lifetime of burglary.
