A good-for-nothing dad, who can hardly cope with his own son, is trusted to take a group of restless children to a summer camp, who are eager to get rid of the adults' care and make Armageddon all around them. Together they manage to get all the children into the train, but they don't manage to get into the train themselves. To prevent the gang of out-of-control kids from derailing the train and saving their own reputations, the two overparents embark on a chase.
