Without ever revealing the diagnosis, this film chronicles the inner life and outer circumstances of Deborah Blake (Kathleen Quinlan), a young mental patient. As the film opens, she is being accompanied by her subdued parents to yet another mental hospital. This one looks clean and cheerful, at least. Her treatment is handled by Dr. Fried (Bibi Andersson), a very skillful therapist who gets past her deranged defenses and reveals that Deborah harbors some very violent fantasies about some of her relatives. The movie is based on the best-selling autobiographical novel by Joanne Greenberg.
