"[2] The swindler Alexander Dupre (Jean-Paul Belmondo) is released from prison ahead of schedule for good behavior, and immediately rushes to make up for lost time during his incarceration.

Posing as an Indian prince, he goes on a cruise ship with the jet set, during which he meets with dazzling beauty Pamela George Eagleton (Mirella D'Angelo), a rich lady, the wife of a diamond mines owner, who has ended up in a difficult financial situation.

Sophie was supposed to seduce him, and then Alexander who was to be introduced as her brother, was going to fake a suicide attempt for the reason of bankruptcy.

But unexpectedly to Sophie, the Duke proposes to her and writes a check for 500,000, and the criminal plan immediately flies out of her head, and the unfortunate "suicide trier" almost loses his life.

The hunt begins for him, and he unsuspectingly under the name of viscount de Valombreza goes to the hotel where he has an appointment with the Japanese, where he intends to sell a fake painting by Canaletto.
