Tom Sawyer meets his friend Joe Harper on his way to school. Joe is convinced that his mother doesn't love him. Because Tom isn't happy at home, the two boys decide to runaway and start a life as pirates. They ask Huckleberry Finn to join them. Tom and Joe leave home after ransacking the foodsupply at home and Huck finds a little dingy at the river. After a little while the boat sinks and the boys head to Jackson's Island where they have the time of their lives, fishing camping and playing pirates. After a day or two the boys hear a big bang. They see the riverboat and a few men loading and firing a cannon to see if someone has drowned. The boys also see aunt Polly, constable Muller and Joe Harper's mother. The runaways become aware that they are the ones that are missing. Huck feels sad that nobody misses him, but Tom and Joe comfort him (thetvdb.com)
