Plot summary
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 ( Eric Thal ), a Swiss conman using the name of Denis Dupont who cheated a group of wealthy investors and romanced their wives. Further evidence reveals that the body is not Foucault, but his assistant Felix Perez. The detectives discover that the investors hired a hitman to teach Foucault a severe lesson. The hitman mistakenly attacked Perez, leaving him alive but Foucault returned to the hotel and brutally killed him, making identification impossible. Goran convinces ADA Carver to indict the investors on false murder charges, while he works in secret to lure Foucault out of hiding so they can arrest him for Perez's murder. Inspired by the life of Christophe Rocancourt.
