Tom Sawyer lives a carefree life in a village on the Mississippi River, only needing to outwit his strict Aunt Polly or his petulant classmates upon occasion. But Tom and his best friend Huck get into real trouble when they witness a grave-robbery-turned-murder, and Tom's testimony makes him Injun Joe's next target. Not even a killer with a vendetta can halt Tom's efforts to win pretty Betty Thatcher's heart, though -- especially once reports of buried gold and unexplored caves arise.
