Bugs accidentally stows away on a riverboat. After evading the ticket taker, he takes on gambler Colonel Shuffle. Bugs easily takes all his money, by out-cheating him at poker (he beats Shuffles 5 aces with 6). Shuffle challenges him to a duel, which of course Bugs thwarts. He treats Shuffle to a cigar, and after the inevitable explosion and blackface, does a quick dance to Camptown Races and escorts Shuffle into the Mississippi. Bugs sends Shuffle into the river again with a fake staging of Uncle Tom's Cabinet. Shuffle is dispatched once more up the ship's smokestack. Finally, Bugs in drag enlists the help of another Southern gentleman.
