The Grinch (Jim Carrey) is a grouchy green monster who lives high up on a mountain overlooking the town of Whoville. The Grinch hates happiness, hates merriment, and most of all, hates Christmas. So one year, as the festive season approaches, he decides that enough is enough and draws up plans to steal all the decorations and all the presents from the poor, unsuspecting citizens below. Does this mean the Whos won't be celebrating this year? Not if little Cindy Lou has anything to do with it.
