Wayne, a Christmas elf, is part of an elite organization known as "Prep & Landing", whose job is to ready millions of homes around the world for Santa Claus's visit. After working with "Prep & Landing" for 227 years, Wayne looks forward to getting promoted. Instead, his former partner and trainee, Peterson, gets the promotion, and Wayne is introduced to Lanny, a rookie whom Wayne has to also train. Wayne is still bitter about the promotion, and decides to slack off during a mission. He permits Lanny to do all of the work, which is disastrous. Meanwhile, Santa is informed mid-flight of a massive snow storm and that Wayne and Lanny haven't fully prepared the house yet. He is told to cancel the landing, which has never happened before; they promise to make it up for Timmy, a boy living at the house. Wayne and Lanny discover that the re-routing was a final decision, but after hearing Timmy thank them in his sleep, Wayne decides to fix it. He calls up Santa, telling him that he must land at Timmy's house. Wayne and Lanny then work together to land Santa safely on Timmy's roof. On Christmas morning, Santa shows Wayne that Timmy had a merry Christmas. Santa offers a promotion to Wayne as the director of the nice list, but he turns it down so he can work with Lanny.
