In an Oregon mental hospital, Nurse Ratched runs a perfectly disciplined ward. The patients follow her every rule and keep no secrets. Enter Randall P. McMurphy, just transferred from prison, with a love for gambling, sex, booze and confrontation. McMurphy bets his new friends that he can unravel Ratched in a week. Told through the foggy haze of Chief Bromden's hallucinations, One Flew Over the Cuckoo's Nest raises the need to question authority and to attack the subtle dulling of the human spirit by institutions.
