Rhinestone (1984)

"She's bet everything, and we mean everything, that she can turn this New York cabbie into an overnight sensation. He has other things in mind. But he's never had a trainer like this one!"

After a big-time country singer brags that she can turn anybody in to a country-singin' star, she's out to prove she can live up to her talk when she recruits a cab-driver as a country singer. He's scheduled to sing at a big-time NYC country night club and she puts her ample powers to work in preparing her protege.
