It all begins when Liz McCann and her son, Mason, leave on a trip to visit Liz's estranged father Jack for Christmas. He gave them instructions, but they just can't seem to find the exact place. Liz was driving, and Mason suddenly tells her to stop. She thinks her son saw something, but it was just a reindeer. Mason runs deep in the forest and sees a town in the valley. He announces to his mother that they have found the place, but Liz can't get the car running. Mason assures her they can walk, it's not that far.
