Independently wealthy Paris detective Max (Michel Piccoli) infiltrates a gang of bank robbers by becoming involved with the leader's girlfriend (Romy Schneider). Working undercover, Max mentions how easy it would be to knock over a certain bank in the hopes that the gang attempts a robbery — so Max, the detective, can catch them red-handed. Never released in U.S. theaters, this taut thriller with a heart of a great melodrama makes its American debut in a restored 35mm print featuring new English subtitles.
