As their owner Andy hits college age, our favourite movie playthings are faced with the prospect of an uncertain future. Will they end up in the trash, locked in the attic or donated to a children's day centre called Sunnyside? Actually it turns out to be the latter and their future looks rather rosy... at first. However, what starts out as a paradise for toys soon turns into a plastic hell and our heroes must hatch a plan to escape and reunite themselves with their beloved owner.
