You've never met anyone like Randle Patrick McMurphy. He's a boisterous, brawling, fun-loving rebel who swaggers into the ward of a mental hospital and takes over. He's a lusty, profane, life-loving fighter who rallies the other patients around him by challenging the dictatorship of Big Nurse. He promotes gambling in the ward, smuggles in wine and women; at every turn, he openly defies her rule. The contest starts as sport (with McMurphy taking bets on the outcome) but soon it develops into a grim struggle for the minds and hearts of the men, into an all-out war between 2 relentless opponents: Big Nurse, backed by the full power of authority, and McMurphy, who has only his own indomitable will.
