Fresh from his escapades with Tom Sawyer, with six thousand dollars in the bank, Huck Finn faces a new challenge: his father, Pap, who wants Huck's fortune and will stop at nothing to get his hands on it.

Escaping from Pap, Huck meets Miss Watson’s slave, Jim, who has run away after learning that Miss Watson may sell him.

Jim plans to head north, find work, and buy his wife and children out of slavery.

Huck joins him on a salvaged raft, beginning a raucous journey that transforms into a deep reckoning with human frailty and the hypocrisy of the antebellum South.
