Just a few days before Christmas, a herd of reindeer are running amok in the London streets, and nine-year-old Tom receives an early festive surprise - in the form of Santa Claus taking shelter in the garden shed! Having crash-landed when testing out his new sleigh, Santa enlists Tom and his father Steve to help him get home to Lapland. Having just been released from prison, all Steve wants is to spend time with his son again, but his plan is thwarted when Santa attempts to liberate his reindeers from Battersea Dogs Home and is thrown into prison himself. It's up to Tom and Steve to get Santa out of prison and save Christmas, while reconnecting with each other.
