A last-minute visit from a hotel inspector throws the Plaza Hotel into a tailspin on Christmas Eve. But the ever-spirited Eloise (voiced by Mary Matilyn Mouser) won't let it derail her plans to put on a holiday extravaganza in the ballroom. While the Plaza's manager, Mr. Salamone (Tim Curry), works the staff into a frenzy, Eloise and her friends continue to rehearse their show -- and keep tabs on Mr. Salamone's troublemaking nephew, Edwin.
