Dr. Derrick Russell (Malcolm McDowell) rapes one of the patients in his care. When the patient throws herself from the roof shortly afterward, he describes her suicide as a consequence of her depression. Ten years later, he plans to rape another patient, Sandy Ramirez (Pamela Gidley). What Russell does not know is that Sandy is the daughter of his previous victim, and she is bent on revenge. A post-credits scene shows Dr. Russell in a padded room kissing the camera and then laughing.
