Rent House of Games (1987)

It's the shrink vs. the shark in the ultimate mind game! When a suicidal patient reveals that his gambling debt has him at the end of his rope, dedicated psychiatrist Margaret Ford (Lindsay Crouse) enters into the shadowy underground world of gaming to help him out. At a seedy casino, she boldly confronts Mike (Joe Mantegna), the con man to whom her patient is in debt. Duped into a high-stakes poker match, Margaret becomes intoxicated by Mike's mastery, as he both cheats at the game and charms her. She quickly falls for him, turning a blind eye to the fact that he's a swindler who can't be trusted. And before long she finds herself sparring in a mental poker match of the heart...with deadly consequences!
