George is fed up with being small. He'd just once like to be able to do things "the regular way." While an afternoon sci-fi flick plays in the background, George, Dad and Junior all find themselves "re- sized." George is the size of your average 10 year old, Dad finds himself George's size and Junior is as big as an elephant. Regular sized George and mini-Dad have to work together to stop giant Junior from wrecking the Shrinks' house before Mom gets home. When Perdita does return, she finds her brood snoozing on the couch, each the exact same size as when she left them.
