During the Christmas season, the small British town of Little Haven is torn apart by a viral outbreak that turns its citizens into blood-thirsty zombies. In this genre mashup, Anna Shepard and her friends are quickly thrown into a fight for their lives as they try to save as many of their friends and loved ones as they can. Of course the action is interspersed with energetic pop songs. According to reviewer Roger Ebert, "It's one of those rare horror movies to leave you with good holiday cheer."
