It is Christmas Eve and the Vanity Fair Mall Santa Claus is nearly finished being jolly old Saint Nicholas for another year. But there is something different about this Santa. He is renting a body from mortal Ken Larsen. Santa listens carefully to Christmas wishes and speaks words of wisdom to each child, but when ten-year-old Billy Mitchell sits on his lap and asks for world peace, Santa suddenly realizes it is the one wish he is unable to grant.
After Ken's shift as Santa ends, he heads to his girlfriend Sandy's home with his red bag on his shoulder. They exchange gifts, and it seems like a peaceful Christmas Eve until the doorbell rings. Suddenly Ken finds himself precariously perched on a dilapidated fire escape outside Sandy's window-with her jealous husband inside. Things go from bad to worse when Ken slips on the icy platform and plunges to his death. But all is not lost when Ken meets Jesus and learns he must return to his body and travel to Israel and help the world make peace. Limited only by Santa's rules, Ken must do everything within his newfound spiritual powers to grant Billy's wish.
In this fictional parable, one man holds the weight of the world on his shoulders as he makes an unprecedented attempt to achieve worldwide peace.
