Tom Sawyer lives with his Aunt Polly and his half-brother, Sid. One day Tom, his friend Joe Harper, and Huck Finn decide to become pirates. The three find a raft and establish camp on Jackson's Island, where they enjoy a carefree life of fishing, swimming, and playing. When a steamboat passes by firing cannons over the water, the boys realize that they are presumed to be drowned. Tom sneaks home at night in order to leave Aunt Polly a reassuring note that they are all right, but he changes his mind when he overhears that church services are planned for the deceased boys if they are not found by Sunday. The funeral services are secretly attended by the boys, and all rejoice when the dead boys casually stroll down the aisle.
