One Flew Over the Cuckoo's Nest

Chief Bromden introduces himself and the world of the ward: Nurse Ratched, the Combine, the fog machine, the Black Boys who enforce order. McMurphy arrives and immediately disrupts the routine.

McMurphy campaigns to watch the World Series. Ratched manipulates a vote to defeat him. He stares at a blank TV anyway — and the other patients join him. A symbolic victory is won.

McMurphy discovers Ratched controls his release date. He stops fighting, becomes model patient. The other men despise his capitulation — until Cheswick drowns and McMurphy understands the cost of his withdrawal.

Ratched's Group Therapy sessions are shown in full: she uses the men's confessions against each other. The fishing trip is arranged — McMurphy maneuvers through bureaucracy and corruption to get the patients outside.

McMurphy reveals he knows Chief has been faking, begins speaking to him as a real person. Chief starts growing again — physically and psychologically. The fog machine begins to clear. They plan the escape.

Ratched escalates her campaign. She posts McMurphy's financial records on the wall, framing him as exploiting the patients. She separates men, controls the story. The ward's fragile hope begins to crack.

McMurphy arranges a night party on the ward: alcohol, prostitutes, chaos. Billy Bibbit sleeps with Candy and is transformed. When Ratched discovers the transgression, she weaponizes Billy's terror of his mother. Billy kills himself. McMurphy attacks Ratched.

McMurphy is lobotomized and returned as a vegetable. Chief smothers him to prevent Ratched from using his body as a warning. Chief lifts the control panel, breaks the window, and escapes into the Oregon dark.
