Fantasy and reality collide in this eclectic and fun musical romp! Emily's having a sleepover with her best friend Stephanie when they discover there's a monster in her closet! To investigate further (despite the incessant teasing of her big brother and his friends), Emily and Stephanie recruit their friends to help capture the monster. What they don't know is that Murray, the closet monster, doesn't mean any harm. He only wants to play Emily's new video game. He's more scared of kids than they are of him! Murray is on probation since his boss, the Dream King, heard about his goofing off on the job. After all, every monster knows that when a child is born, a monster is assigned to watch over her not play with her things! What happens when Emily has all her friends over for a slumber party to try to capture Murray?
