The amazing journeys of Baron von Munchausen, who sets sail in a hot air balloon in search of his old comrades-at-arms with the object of saving a European city from the superior forces of a Turkish sultan.

Sixth-grader Peter is pretty much the average kid, he likes gaming, hanging with his friends and his beloved pair of Air Jordans. But when his recently widowed grandfather moves in with Peter's family, the boy is forced to give up his most prized possession of all, his bedroom. Unwilling to let such an injustice stand, Peter devises a series of increasingly elaborate pranks to drive out the interloper, but Grandpa Ed won't go without a fight.
