What's the story?
Trouble comes to a small Iowa town when conman "Professor" Harold Hill (Robert Preston) arrives, posing as a salesman of band instruments and uniforms. Hill happens upon an old friend, Marcellus Washburn (Buddy Hackett), and is ready to run his favorite scam on the folks of River City. He plans to sell the town on the idea of a boys band, with himself as leader, get them to order instruments and uniforms, then skip town with the money. But first he must convince the skeptical citizens, including reserved librarian and music teacher, Marian (Shirley Jones), who lives with her widowed mother (Pert Kelton) and her shy little brother Winthrop (Ronny Howard). Hill is able to dazzle the town, even Marian. Despite evidence that he does not have the credentials he claims, and her certainty that he is not what he pretends to be, she finds herself softening toward him and protecting him. Because of her, he stays too long, and he is arrested. But somehow, the boys force a few sounds out of the instruments, enough for their proud parents. And Harold stays on -- it turns out that all along, deep inside, what he really wanted was to lead a band.
