The wife of Casino owner Maxine Beauregard is poisoned to death in front of his friends and assistant. Camille and Lea are called to the scene, and all suspicions point toward the blacklisted gambler Roxie Roland. The problem is, there is no proof. After their mutual deal, Camille teams up with Harry, trying to solve the murder. As a conman, there is no one better suited than to take down another con woman. But as the evidence and the suspects pile up, it takes a high-stakes poker game to unravel the truth. With Camille's father in prison, Harry keeps his end of the bargain and gives Camille the name of the man threatening her father. He is already in Cannes.
