Henri Verdier, a young bank manager, has made the acquaintance of Karine, a model of great beauty. Robert, who claims to be Karine's brother, forces Karine to introduce him to Verdier. This is to offer him an urgent business deal: 50 million for a uranium purchase which, within a few days, should yield double that amount. Blinded by passion, Verdier accepts and "withdraws" the necessary sum from his bank. He soon realizes he's been duped. Karine is not Robert's sister and Robert is a crook. Verdier tracks them down.
