Psychiatrist Dr. Dean Brooks, who appears in the film One Flew Over The Cuckoo's Nest, and others discuss how jails and prisons have become our new asylums and how community care, especially inadequately funded community care, is failing to help people. They also discuss the need for what his granddaughter, Dr. Ulista Brooks, describes as “true asylums” — the construction of new modern mental hospitals, and other important issues regarding care for the mentally ill.
Randle McMurphy (Jack Nicholson), un violador de espíritu libre, que vive contracorriente, es recluido en un hospital psiquiátrico.

La suerte de cada paciente del pabellón está en juego.
