It's Halloween, and all of the residents of the Plaza Hotel are in good spirits. But when the infamous ghost of Diamond Jim Johnson surfaces to wreak havoc, it's up to Eloise (voiced by Mary Matilyn Mouser) and her friends to put him in his place. Lynn Redgrave, Tim Curry, Brad Garrett and Jim Belushi lend their vocal talents to this delightful addition to the Eloise universe, inspired by the beloved books by Kay Thompson.
