If Roy "Tin Cup" McAvoy had played it safe, he might have been golfing on the pro tour instead of giving lessons at a driving range in the tiny West Texas town of Salome. And he wouldn''t be sacrificing his dignity to David Simms, a PGA star and longtime rival, by accepting a job as his caddie. Roy should have controlled what his best friend, Romeo Posar, called his "inner demons." When Dr. Molly Griswold walked onto his green, he should have settled for giving the lady psychologist golf lessons and never allowed himself to fall in love with her. But something about Molly''s rational mind, her sharp wit, and her long legs makes it clear to Tin Cup that once again, he''s not going to play it safe. Even though she''s already Simms'' girlfriend. Roy has to win Molly with a gesture so grand that nothing less than her undying adoration would be an appropriate response. And suddenly, inspiration strikes: All Roy has to do is win the U.S. Open - the most difficult tournament in the pro golfing world.
