【簡介】
1963年的燦爛夏日，懷俄明西部，年輕的牛仔傑克·特維斯特(傑克·吉倫希爾飾)與恩尼斯·德爾瑪(希斯·萊吉飾)因同為牧場主喬·阿桂爾(蘭迪·奎德飾)打工而相識，傑克比較健談，且騎術高超，恩尼斯自幼父母雙亡，性格內向寡語。人跡罕至的斷背山深處，高山牧場的放羊工作單調而艱苦，隨時有遭遇野獸襲擊的可能，一人不得不看守羊群，和羊群睡在一起。起初二人一個放羊，一個看營地，少有交流。直到有一天，二人晚飯時喝多了酒，是夜又分外寒冷，於是傑克與恩尼斯同帳共裘而眠，在酒精與荷爾蒙的作用下，他們之間發生了“不該發生的事”。
空虛寂寥讓兩個19歲的青年彼此相愛了，一個人做飯，另一個放羊，篝火邊長談，帳篷內歡愛，同性間的純美真愛伴隨二人度過了人生中最美好的一段夏日時光。

Ennis Del Mar wakes before five, wind rocking the trailer, hissing in around the aluminum door and window frames.
The shirts hanging on a nail shudder slightly in the draft.
He gets up, scratching the grey wedge of belly and pubic hair, shuffles to the gas burner, pours leftover coffee in a chipped enamel pan; the flame swathes it in blue.
He turns on the tap and urinates in the sink, pulls on his shirt and jeans, his worn boots, stamping the heels against the floor to get them full on.
The wind booms down the curved length of the trailer and under its roaring passage he can hear the scratching of fine gravel and sand.
It could be bad on the highway with the horse trailer.
