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 he has to give up his most prized possession -- his bedroom -- when his recently widowed grandfather moves in with Peter's family, he's 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.
