Build a movie plot around this: Who is Mac's ex-wife? Dixie Scott, a country music star
A:
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.Mac resolves to give up alcohol and start his life anew. After some time passes, he and Rosa Lee wed. They start attending a Baptist church on a regular basis. One day, a newspaper reporter visits the motel and asks Mac whether he has stopped recording music and chosen an anonymous life. When Mac refuses to answer, the reporter explains he is writing a story about Mac and has interviewed his ex-wife, Dixie Scott (Betty Buckley), a country music star who is performing nearby.After the story is printed, the neighborhood learns of Mac's past, and members of a local countrywestern band visit him to show their respect. Although he greets them politely, Mac remains reluctant to open up about his past. Later, he secretly attends Dixie's concert. She passionately sings several songs that Mac wrote years earlier, and he leaves in the middle of the performance. Backstage, he talks to Dixie's manager, his old friend Harry (Wilford Brimley). Mac gives him a copy of a new song he has written and asks him to show it to Dixie. Mac tries to talk to Dixie, but she becomes angry upon seeing him and warns him to stay away from their 18-year-old daughter, Sue Anne (Ellen Barkin).Upon his return home, Mac assures Rosa Lee he no longer has feelings for Dixie, whom he describes as "poison" to him. Later, Harry visits Mac to tell him, seemingly at Dixie's urging, that the country music business has changed and his new song is no good....
