Book: One Flew Over the Cuckoo's Nest

I am reading 'One Flew Over the Cuckoo's Nest' by Ken Kesey for my English II Honors class. It is about "Chief" Bromden, a schizophrenic  Native American man who pretends to be deaf and dumb so that everybody ignores him, narrates  One Flew Over the Cuckoo’s Nest. The novel begins the morning that a new "Admission," Randle McMurphy, is introduced to an insane asylum where Chief is the longest-residing patient. McMurphy is larger than life, intelligent, and observant. He stirs up the ward immediately by introducing friendly competition – gambling – and encourages the men to rebel against the petty rules created and enforced by Nurse Ratched (often referred to as "Big Nurse"). McMurphy places a bet with the other men on the ward that he can break Nurse Ratched without: a) getting sent to the Disturbed Ward, b) getting treated with electroshock therapy, or c) being lobotomized. Slowly, McMurphy undermines Nurse Ratched’s system of control while remaining Mr. Nice Guy. She’s no fool, however. What McMurphy doesn’t understand is that Nurse Ratched has a lot of control over the situation. Since he’s a patient in the asylum, she can keep him locked up as long as she wants. As long as he’s under her rule, she has the power to send him for electroshock therapy or a lobotomy. The question is simply whether she’ll utilize her power against him or not. When McMurphy figures this out, he steps back and begins to behave – but not for long [source:http://www.shmoop.com/one-flew-over-cuckoos-nest/summary.html]
