Tom has to choose between honoring a friendship or honoring an oath because the town alcoholic is accused of the murder. Tom and Huck go through several adventures trying to retrieve evidence.

Mischievous Huck Finn is unnerved when his father, reemerging after years away, kidnaps him in an attempt to take away a $600 inheritance from his late mother.

Together, the pair embarks on a raft journey down the Mississippi River, staying ahead of pursuers who blame the slave for Huck's alleged murder.
