Peter (Oakes Fegley) and his Grandpa Jack (Robert De Niro) used to be very close, but when Grandpa 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. But, Grandpa doesn't give up easily and before long, it's an all out war!

Directed by Tim Hill and the screenplay was written by Tom J. Astle and Matt Ember.
