Detectives Goren and Eames investigate the murder of a man found beaten to death in a hotel suite. It appears the victim was Didier Foucault, a Swiss conman who cheated a group of wealthy investors and romanced their wives, but further evidence reveals that the dead man is not Foucault, but his assistant Felix Perez. The detectives discover that the investors hired a hitman to teach Foucault a severe lesson, but that he learned of the attack and sent Perez to his hotel room in his place. The hitman attacked Perez, but left him alive, and Goren begins to suspect that Foucault returned to the hotel and killed him. ADA Carver indicts the investors on false murder charges, in an attempt to lure Foucault out of hiding so they can arrest him for Perez's murder. Inspired by the life of Christophe Rocancourt.
