When little children find presents near the tree on New Year’s morning, they believe that Santa Claus brings them. Nine-year-old Thomas, the hero of this movie, also believes in him. He is obsessed with the idea of catching the elusive Santa Claus. To the dismay of his mother, Thomas has turned their house into a testing ground for the game, installing video cameras in all rooms, traps, nets, equipped with secret passages. On the evening before Christmas, Thomas hides under the dining room table and waits in ambush, unaware that he will have to live through the worst night of his life. A ruthless duel pits the kid against a psychopathic killer.
