The film tells the story of 6-year-old girl Muni and her mother Hayley. They live a worn motel, named “The Magic Castle”, which is not far from local Disneyland.
Some tourists inadvertently confuse the motel with the official hotel of the park. Children of local lone mothers, who often work as staff in the moon park, are left alone to take care of themselves. Little Mooney, Skuti and Yancy regularly search for interesting activities.
