On Jackson Island Huck and Jim are hiding in a cave when a massive storm suddenly breaks loose and devastates the island.

There he finds that a high ransom has been put up for the capture of Jim. Huck and Jim decide that their hiding place on the island has become too dangerous and so they start their journey down the Mississippi on the raft.

Huck and Jim build a shelter for Jim on their raft for Jim to hide in when other boats come near them. When this actually happens Huck tells the boatmen that his very sick father,who is suffering from Smallpox is sleeping there. The men are afraid and leave as fast as they can. On the same day Jim and Huck lose each other when a river steamboat colides with their raft and sinks.

Tired and worn out after the raft accident Huck comes across a large farm estate a few hundred yards from the river. After some initial scepticism the Grangerford family who live there take pity on Huck and welcome him into their home. They explain to him that they were afraid he may have been a member of a rival family called the Shepherdsons whom they are having a live in feud with. Huck fakes his identity and introduces himself as George Jackson. He settles in well with the family, making good friends with one of the boys, Buck, and even being awarded his own slave. However on a hunting trip Huck soon realises the true scale of the feud when Buck spots and attempts to shoot one of the Shepherdons from his horse.

Huck is entangled further into the feud between the Grangerfords and the Shepherdsons and realise that he himself is now as much a target as any of the family. He discusses the feud with Buck who informs him that it goes way back in time, though even he can't recall why it ever started and why it still exists. On accompanying the family to Sunday services Huck is astonished to witness the men carrying rifles to the church. The Shepherdsons also attend the same service with their own rifles. On returning from the service the beautiful Sophia Grangeford asks Huck for a favour. She informs him that she has forgotten her Bible at the services and wishes for him to fetch it for her. When Huck does so a note saying ‘half-past two' slips out of the Bible. Huck replaces it and returns it to a clearly delighted Sophia. Huck's slave Jack meanwhile is keen for Huck to see a breed of rare snakes down by the river. Huck reluctantly obliges and soon finds out the true reason behind Jack dra

When Huck returns to the Grangefords he finds that the house is empty. His slave Jack informs him that the feud has erupted after Sophia took off to marry one of the Shepherdon boys. Huck now realises the significance of the note in the Bible. He finds the families amidst a brutal shootout in the forest and from high up in a tree he witnesses a sad and bloody end to the lives of many of the Grangefords who had treated him so well. A dejected Huck makes his way back to the raft where he and Jim set sail again.

Upon resuming their travels down the Mississippi Huck and Jim encounter two strangers whom they pick up and save from a group of chasing gunmen. The pair pretend to be royalty so that they get treated well with one calling himself a Duke and the other calling himself The Dauphin (the King of France). Jim is taken in by all this but, while Huck does not believe a word of it, he doesn't wish to get on the wrong side of them in case they report Jim as a runaway slave and so plays along. On the raft it becomes apparent that the two are actors as they act out scenes from ""Romeo and Juliet"". The pair plan on running a play in the next town they come across.

The Duke and the Dauphin rehearse their wacky Shakespeare-act on the raft. The Dauphin falls into the water but Huck manages to help him back on the raft again.
