Three-year old Cecil Luna is afraid of the dark. He frequently wakes up wanting to sleep with his parents because he believes there's a ghost in his room. To help him overcome his fear of the dark, his mother throws a special Halloween party. The neighborhood kids dress up as monsters, scaring Cecil with the ghastly chant he hears when he wakes up at night in his room. When he discovers the monsters are only the neighborhood kids in costume, Cecil dresses up as a werewolf, joins the party, and declares himself no longer afraid of the dark. After the party, Cecil's father reveals the family legend: Some trick and treaters are real ghosts who still crave sweets. It's essential to leave candy and treats to appease them. If you don't, they can get in the house. Once they're inside, says his father, the only way to get rid of them is to trick them. What do you think happens one Halloween when the family goes to visit Grandma, but forgets to leave treats and goodies?
