Dream Lover (1994)

Not long after they cross paths at an art gallery, Ray Reardon (James Spader), an architect, and hypnotically sensual Lena (Madchen Amick) are married with children. Only then does Ray catch his wife in escalating lies, which lead him to find out that Lena's past is invented and that she has been manipulating him ever since their first chance meeting. In the ensuing turmoil, Lena ends up with Ray's money, and he winds up in an institution -- from which he plots his return and revenge.
