Lone Star takes place in the cluttered backyard of a small-town Texas bar in 1972. Roy, a brawny, macho type who had once been a local high-school hero, is back in town after a hitch in Vietnam and realizes that about all he has left are memories of his glory days, his adoring younger brother Ray, his wife Elizabeth, and his now-crumbling 1959 pink Thunderbird. Joined by Ray, Roy sets about consuming a case of Lone Star beer while regaling his brother with tales of his military and amorous exploits. But with the arrival of Cletis, the fatuous, newlywed son of the local hardware store owner, the underpinnings of Roy’s world gradually begin to collapse.
