The terror in this erotic horror thriller begins in the past when Dr. Russell, the director of a mental hospital, rapes a patient who afterward kills herself. Many years pass and the main story begins when a lovely model checks into the asylum. Dr. Russell feels those old lustful, violent stirrings upon seeing her, but during the drug-induced "seduction" something goes terribly wrong and the model seems to have died. With the aid of his weird staff, the doctor tries to get rid of the body, which mysteriously vanishes by the next day. Later, the shrink begins to seriously question his own sanity when he keeps seeing the form of the model surreptitiously sneaking around the grounds. Things only get stranger from there.
