Book "Flight Will Fly Over" by Ken Keese

This work has left a deep mark on modern literature. Turning conventional notions of sanity and madness upside down, this wild novel is the unforgettable story of a mental hospital and its residents, where the tyrannical Big Sister and McMurphy, a noisy fun-loving newcomer, are at odds. The struggle is told through the eyes of Bromden, a half-Indian, seemingly deaf and dumb patient who understands. McMurphy makes heroic efforts to fight against the forces that keep them all locked up.
