Mac Sledge (Robert Duvall), a washed up, alcoholic country singer, awakens at a run-down Texas roadside motel and gas station after a night of heavy drinking. He meets the owner, a young widow named Rosa Lee (Tess Harper), and offers to work in exchange for a room. Rosa Lee, whose husband was killed in the Vietnam War, is raising her young son, Sonny (Allan Hubbard), on her own. She agrees to let Mac stay under the condition that he does not drink while working. The two begin to develop feelings for one another, mostly during quiet evenings sitting alone and sharing bits of their life stories.
