Dr. Matthew Stern is a psychiatrist with a successful but disappointing practice. One day an attractive woman enters his office, detailing a highly sexual, if somewhat disturbing recurring dream. The doctor's concern for this patient quickly borders on erotic obsession, and his involvement becomes far too intimate, threatening both his marriage and his practice. Melissa Myles is the mysterious psychiatric patient who insinuates herself into Dr. Stern's personal and professional life. Is she truly just a disturbed mental patient or something far more sinister? The doctor, along with his devoted wife and his best friend/mentor, is determined to discover how and why this cunning seductress has turned his life upside down.
