Larry Guthrie, who loses his first love to the town hot shot, decides to win her back by volunteering with the children at her after-school program. When Larry accidentally tells the kids the Tooth Fairy is make-believe, he soon is transformed into a tutu-clad fairy with the "sentence" of collecting teeth.
