The Adventures of Huckleberry Finn (1984)

Huck is kidnapped by his father but manages to fake his own death and escape to Jackson's Island, where he coincidentally meets up with Jim, a slave of the Widow Douglas' sister, Miss Watson. Jim is running for freedom because he has found out that Miss Watson plans to "sell him South" for $800. Together they construct a raft and travel on the Mississippi River, Jim hoping for freedom from slavery, and Huck searching freedom from his drunk father and controlling foster parent.
