"The summer ends and both men go off to the rest of their lives. Ennis marries his
sweetheart Alma (Michelle Williams), and Jack, moving to Texas, falls into a marriage with Lureen (Anne Hathaway), a rodeo rider with a well-to-do father. They think that what happened on Brokeback Mountain is over, but it is not. For what Ennis and Jack reluctantly come to realize is that, all unawares, they have stumbled into the great love of their lives, with all the problems and complications that implies for themselves and the others in their
life. In a profound sense, because of the pressures of the time and place they live in, they are lost whether together or apart, riven by the agonizing longing they feel, by the chances not taken and the choices just out of reach."
