Young cowboys, Jack Twist and Ennis Del Mar, are hired to corral sheep on the title location and they soon bond very closely. Their platonic relationship explodes into a physical one, but eventually the two are separated when their job comes to an end. Although the two follow different life paths -- one becoming a father of two and the other marrying into a successful business -- they have a reunion years later. Each is affected profoundly by the rekindling of their old feelings for each other. Those feelings lead each to consider what continuing their hidden relationship would cost them.
