Who wants to live in a house, wear clean clothes, be good, and go to school every day? Not young Huckleberry Finn, that's for sure. So Huck runs away, and is soon floating down the great Mississippi River on a raft. With him is Jim, a black slave who is also running away. But life is not always easy for the two friends. And there's 300 dollars waiting for anyone who catches poor Jim . . .
