A boy made for mischief, Tom constantly grieves his Aunt Polly with his cunning tricks to get out of school and to lead an idle life of swimming and larking by the banks of the Mississippi. His scrapes vary from whitewashing a fence to witnessing a murder and from running away to be a pirate to hunting by night for buried treasure - but each episode ends with Tom ingeniously on top, as the hero of the village and the envy of all the other boys.
