A successful psychiatrist (Cassavetes) has his world turned upside-down by the appearance of a mystery woman (Whirry) who cannot recall her own past. Along with a friend (Roundtree), he tries to unlock her secret only to uncover a bizarre series of events.
At least one of the clients that the doctor fucks (at 47:00) has a male partner (named Leonard, according to her). At 69:30, a husband comes to the doctor's office and punches him for suggesting to his wife about having an affair. I think that his wife is not the one at 47:00 but the one at 30:30.
