Meet Santa. He's having a mid-life crisis. He hates his job and wishes he was doing anything else other than being Santa. He's just going through the motions and that's why he doesn't notice the zombie apocalypse until it's almost too late. Saved by two kids, he at first tries to get back to the North Pole only to discover that his reindeer have been eaten. On the run and just trying to survive, Santa befriends the kids and falls in love with their recently-divorced mother. Soon Santa rediscovers his Christmas spirit and does everything he can to save Christmas for the kids--even if it means his own death.
