Have you ever wondered if Santa and the Tooth Fairy would show up at your house on the same night or who would replace Santa if he retired? Well, wonder no more. This soon-to-be classic Christmas story starts with an impish young boy, Nate, losing a tooth on Christmas Eve. When Santa and the Tooth Fairy arrive, Nate learns some shocking news about the couple. He also learns that the jolly old elf plans to retire, and Nate will have a chance to become the next Santa.

Nate comes to a week-long Santa Camp to compete for the position. At camp, we meet Randy the Elf, learn more about Rudolph, discover how reindeer fly, and follow eight boys as they endure various tests and training to see which one has the "right stuff" to be the next Santa.

One by one, the boys are eliminated until only three remain. Nate, and two others, are invited to accompany Santa on a ride-along the next Christmas Eve. On his final test, with Christmas teetering near disaster, can Nate save the day?
