Plot Psychiatrist Margaret Ford has achieved success with her recently published book about obsessive-compulsive disorder, but feels unfulfilled. Her patient, Billy Hahn, says his life is in danger because he owes money to a criminal figure named Mike Mancuso. He threatens suicide, brandishing a gun. Margaret persuades him to surrender the weapon to her and promises to help him. That night, Margaret visits a pool hall called House of Games where she confronts Mike. He is willing to forgive Billy's debt if Margaret accompanies him to a back-room poker game and watch for the tell of George, another player: he plays with his ring when he bluffs. She agrees, and notices George playing with his ring after making a big bet. She discloses this to Mike, who calls the bet. However, George wins and demands that Mike pay the $6,000 bet, which he is unable to do. George pulls a gun, but Margaret intervenes and offers to pay the debt with a personal check. She then notices the gun is a water pistol, and realizes the entire game is a set-up for her money. She declines to pay, but spends the rest of the night socializing with the con men. The experience excites her and she returns the next night. She asks Mike to teach her about con games so she can write a book about it. Mike appears skeptical, but agrees. Margaret is enchanted by Mike showing her simple con tricks. Eventually, the two sneak into a hotel room and have sex. Afterward, Mike tells Margaret that con artists take a small token from every "mark" to signify their dominance. While Mike is in the bathroom, she takes a small pocket knife belonging to the room's occupant. Mike says he is late for another large-scale con that he and his associates are planning at the same hotel. Mike reluctantly allows her to tag along, posing as his wife. The con involves Mike, his partner Joey, and the "mark", a businessman, discovering a briefcase full of money and taking it to a hotel room. They discuss whether to turn it in or split it among themselves. When the "mark" withdraws to the bathroom, Margaret discovers that he is an undercover cop part of a sting operation. She warns Mike, and they attempt to escape, but the cop tries to arrest them.
