In this exuberant musical version of Mark Twain's classic novel, Tom Sawyer (Johnny Whitaker) lives with his exasperated Aunt Polly (Celeste Holm) in the riverfront town of Hannibal, Missouri. Along with his rag-tag best friend Huckleberry Finn (Jeff East) and his sweetheart Becky Thatcher (Jodie Foster), Tom's life is a series of clever and irrepressible adventures. But when he and Huck witness a crime, Tom must decide if he will risk his life to exonerate town bum Muff Potter (Warren Oates).
