Peter and his grandpa used to be very close, but when Grandpa Jack moves in with the family, Peter is forced to give up his most prized possession: his bedroom. Peter will stop at nothing to get his room back, scheming with friends to devise a series of pranks to drive him out. However, grandpa doesn’t give up easily, and it turns into an all-out war between the two.
