Who knew holding a grudge could cause so much trouble? It does when the Grudge is a real-life downer that won’t go away, won’t leave you alone and brings all of his crummy friends along to bug you, too! It all starts simple enough, with a borrowed sweater mishap that eventually involves Gretchen’s sister, best friend and brother. Gretchen begins holding a grudge against all of them. Literally. The Grudge, who loves being held and sits on the couch next to her, invites his friends — the Moodkeeters, Peevish and Hothead, and finally the dreaded Doldrum family — all of whom hang onto Gretchen. As she sinks deeper into the doldrums, her friends and family desperately try to come up with ways to get her back to herself. Nothing seems to work until at last Gretchen comes to a realization in a musical and happy ending: only she can be responsible for getting rid of the Grudge and all his friends.
