It is the story of a boy who lives in a small city in the southwestern United States on the banks of the Mississippi. Raised by his Aunt Polly who loves him from the heart but what to a discipline that makes him absurd and unpleasant. Tom looks at the world in a very different way than the adults with whom he has to live. Precisely because that distancing exists, it entertains with its amusing and noble reactions. More wild and rebellious against that universe of older people is his friend Huckleberry Finn, Tom's ideal companion who is envied by the other children who contemplate in his life a form of existence that they would like to lead. Together they will live humorous and dramatic adventures that can come out more airy than any adult could do. In the end, both Tom and Huck will end up being led in that context of people who will grow up and stop being children.
