英文介紹：

　　Randle Patrick McMurphy (Nicholson), a criminal who has been sentenced to a fairly short prison term, decides to have himself declared insane so he'll be transferred to a mental institution, where he expects to serve the rest of his term in (comparative) comfort and luxury.

　　His ward in the mental institution is run by an unyielding tyrant, Nurse Ratched (Fletcher), who has cowed the patients, most of whom are there by choice, into dejected institutionalized submission. McMurphy becomes ensnared in a number of power games with Nurse Ratched for the hearts and minds of the patients. All the time, however, the question is just how sane any of the players in the ward actually are.

　　Throughout his short stay at the hospital, McMurphy forms deep friendships with two of his fellow patients: Billy Bibbit (Dourif), a suicidal, stuttering manchild whom Ratched has humiliated and dominated into a quivering mess; and "Chief" Bromden (Sampson), a 6'5" muscular Native American who has schizophrenia. Recognized by the patients in the ward as deaf, and unable to speak, they ignore him but also respect him for his enormous size. In the former, McMurphy sees a younger brother figure whom he wants to teach to have fun, while the latter is his only real confidant, as they both understand what it is like to be treated into submission.

　　McMurphy initially insults Chief when he enters the ward, but attempts to use his size as an advantage (for example, in playing basketball, for which his height is favourable). Later, both are suspended, along with patient Charlie Cheswick (Lassick), for being involved in a fight with the male nurses, and are sent to a detention area. Cheswick is sent first to undergo shock therapy, while McMurphy and Chief wait on the bench. During this time, McMurphy offers Chief a piece of gum, and Chief verbally thanks him. A surprised McMurphy realizes that Chief can speak and has actually been faking his situation at the ward the whole time. This leads McMurphy to allow Chief in on his escape plan because of his hidden wisdom. Ending this scene, a more defiant McMurphy emerges from the detention area to an awaiting Nurse Ratched.

　　One night, December 10, 1963, McMurphy sneaks into the nurse's station and calls his girlfriend to bring booze and assist in his escape. She brings a girlfriend, and both enter the ward. The patients drink, while Billy flirts with McMurphy's girlfriend.

　　Nurse Ratched commands the nurses to clean up the patients and conduct a head count. When they discover that one patient is missing, Nurse Ratched threatens to tell Billy's mother and he begs her not to. When she explains that he should have thought of the consequences, he breaks down into tears. When left alone momentarily, he commits suicide. After McMurphy sees what the ward has done to his friend, he explodes into a violent rage, strangling Nurse Ratched until she is near death. She survives, but McMurphy is taken away yet again for punishment-a lobotomy operation.

　　Chief, unwilling to leave McMurphy behind, suffocates his vegetable-like friend with a pillow. "I'm not goin' without you, Mac. I wouldn't leave you this way. You're coming with me." He lifts a heavy marble hydrotherapy fountain and, hurling it through a barred window, escapes to Canada.

　　簡(jiǎn)介

　　麥克默菲由于厭惡監(jiān)獄里的強(qiáng)制勞動(dòng)，裝作精神異常而被送進(jìn)了精神病院。自從他來(lái)到后，本來(lái)平靜的精神病院就發(fā)生了一連串的事件。

　　精神病院遠(yuǎn)非是麥克默菲想像中的自由的避難所。護(hù)士長(zhǎng)拉契特制定了一整套秩序，一切都要以此為準(zhǔn)則。病人們受到了嚴(yán)格的管制，還不時(shí)的受到她的侮辱和折磨。麥克默菲對(duì)拉契特的行為十分不滿，不時(shí)以冷嘲熱諷的方式對(duì)她加以攻擊。在精神病院里，病人們被剝奪了自由地追求自己生存欲望的力量。拉契特處處和麥克默菲為難。她用大音量的刺耳音樂(lè)折磨病人們，并冷酷地拒絕降低音量的要求。在酷愛(ài)棒球的麥克默菲提出看世界錦標(biāo)賽的實(shí)況轉(zhuǎn)播時(shí)，拉契特又想方設(shè)法推搪拒絕。雖然麥克默菲最后得到了高大的印第安人“酋長(zhǎng)”的支持，湊夠了表決的票數(shù)，但拉契特卻又以表決時(shí)間已過(guò)為借口而拒絕打開(kāi)電視機(jī)。

　　麥克默菲想讓病人們打起精神，快樂(lè)的生活一天。他把病人們帶上了汽車，來(lái)到了一個(gè)小港口。他們偷了一條船，到遠(yuǎn)海釣魚作樂(lè)。病人們欣喜若狂，過(guò)了十分快樂(lè)的一天。回來(lái)后，麥克默菲受到了懲罰。但不久，他就又把自己的女友和另一個(gè)女人弄到了醫(yī)院，鬧得天翻地覆。聞迅趕來(lái)的拉契特侮辱了病人比利，使他割脈自殺，而冷酷的拉契特卻無(wú)動(dòng)于衷。這使原想要逃離病院的麥克默菲再也抑制不住怒火，他撲上去掐住了拉契特的脖子。拉契特沒(méi)有死，可麥克默菲卻受到了最慘無(wú)人道的待遇。病院切除了他的腦白質(zhì)，使他成了一個(gè)完完全全的白癡。“酋長(zhǎng)”悲痛地將他摟在懷里，用枕頭悶死了這個(gè)實(shí)際上已經(jīng)死亡的生命。

　　之后，“酋長(zhǎng)”砸開(kāi)了鐵窗，逃出了這個(gè)令人窒息的地方。
