When Randle Patrick McMurphy (Jack Nicholson) gets transferred for
evaluation from a prison farm to a mental institution, he assumes it
will be a less restrictive environment. But the martinet Nurse Ratched
(Louise Fletcher) runs the psychiatric ward with an iron fist, keeping
her patients cowed through abuse, medication and
sessions of electroconvulsive therapy. The battle of wills between the
rebellious McMurphy and the inflexible Ratched soon affects all the
ward's patients.
