McMurphy's revolt ends in lobotomy, Chief escapes
Randle McMurphy, a convict who fakes insanity to escape a prison work farm, learns that as an involuntary committed patient his release depends entirely on Nurse Ratched. His rebellions—a vote to watch the World Series, a fishing trip, a smuggled ward party—culminate in his attacking Ratched after she shames the stuttering Billy Bibbit into suicide, and he is lobotomized. Chief Bromden, who had feigned deafness and muteness for years, smothers McMurphy's vegetative body and escapes by throwing the hydrotherapy control panel through a window, a panel McMurphy had failed to lift earlier.
