Tom Sawyer, a shrewd and adventurous boy, is as much at home in the respectable world of his Aunt Polly as in the self-reliant and parentless world of his friend Huck Finn. The two enjoy a series of adventures, accidentally witnessing a murder, establishing the innocence of the man wrongly accused, as well as being hunted by Injun Joe, the true murderer, eventually escaping and finding the treasure that Joe had buried.
