Ken Kesey's classic novel is set in a state mental institute in 1950s America. Nurse Ratchet runs the ward like a military operation, weaponising shame, fear, and manipulation to keep the patients compliant. She maintains this façade of politeness and professionalism while emotionally castrating the men in her care, who have internalised the notion that they are deeply broken and can’t survive freedom outside the hospital. All this changes at the arrival of a new patient named Randle Patrick McMurphy.
