Dangerous Dan (William Shatner) is an alcoholic radio DJ stuck pulling a long shift at the small town radio station CTRM in Bailey Downs, Ontario during Christmas Eve. During his broadcast, a series of four untitled stories are witnessed concurrently:

First story

Dylan (Shannon Kook), Ben (Alex Ozerov), and Molly Simon (Zoé De Grand Maison) are three teenagers who have decided to break into their school, which used to be a convent, in order to investigate two murders that occurred in the school's basement the year prior. Their friend, Caprice (Amy Forsyth), was supposed to go, but she instead has to go with her parents out of town. The three of them end up getting locked in the basement. Molly becomes possessed after witnessing a bloody ghost and tries to seduce the others. When Dylan refuses her, Molly kills him. Ben agrees to have sex and after the act is finished, the ghost leaves Molly's body. Upon waking Molly, reveals that the ghost is actually a pregnant teenager who died many years ago when the school was a convent after the convent's nuns gave her a gruesome surgery to remove the baby. The ghost is only interested in having someone give birth to her child and if someone refuses, they're murdered explaining last year's deaths. Despite impregnating Molly, the ghost sees Ben holding a weapon which the ghost views a threat, and the ghost kills him. The ghost then unlocks the door and allows Molly to leave.

Second story

Scott (Adrian Holmes) is a police officer (one of the policemen who investigated the two murders at the high school the previous year), but this doesn't stop him from going into woods owned by "Big Earl" (Alan C. Peterson) with his family to illegally chop down a Christmas tree for his family. During the trek, Scott's nine-year-old son Will (Orion John) wanders off and is lost. He and his wife Kim (Olunike Adeliyi) manage to find Will inside of a tree and are overjoyed to find him. This joy is short lived after Will begins to act strangely, culminating in Big Earl contacting the family to warn them that Will is actually a changeling; a clone of the original Will. After the changeling kills Scott, Kim brings the changeling to Big Earl, who states that he's unable to help her find her son because it is up to the changelings. This ultimately ends with Kim shooting Big Earl, who was actually the changeling's abusive master. Finally free, the changeling returns to his home and frees Will allowing him to go home with his mother Kim.

Third story

Caprice (the friend of the teens Dylan, Ben and Molly from the first story) and her younger brother Duncan (Percy Hynes White) are traveling with their bickering and verbally abusive parents in order to visit their elderly Aunt Etta (Corrine Conley). During their visit, Etta tells them about the mythological creature Krampus (Rob Archer), which frightens Caprice especially after Duncan purposely misbehaves in an attempt to irritate Etta's caretaker, Gerhardt (Julian Richings). Their parents decide to take the children home at Etta's insistence but on the way the family ends up getting into a car accident, making it necessary for them to walk. Aware that they were being hunted by Krampus because they acted badly, the family members take refuge in a church where they confessed their sins in belief that Krampus will leave them if they do so. However, they are killed off one by one until only Caprice remains. Caprice manages to flee to Great-Aunt Etta's house. She is successful in killing Krampus who transforms into Gerhardt. It's revealed that he transformed into Krampus due to his anger over the family's actions and that Etta was fully aware that this would happen. Furious, Caprice's anger causes her to transform into Krampus and she attacks and kills Etta.

Fourth story

While preparing for a busy Christmas at his North Pole castle, Santa Claus (George Buza) discovers that all of his elves and his wife Martha have turned into zombies after one of the infected elves dies following a fit of rage. He manages to kill them all, but is then forced to fight against Krampus in the stables. However, during the battle, it's revealed that "Santa" is actually a Mall Santa named Norman (who was an earlier guest on Dangerous Dan's radio show) that had a psychotic break while working overtime that caused him to see regular mall goers as zombies during the Christmas Food Drive. This whole 'Santa' segment is actually taking place in Norman's mind. The police arrive and manage to gun him down just as he's about to kill "Krampus", revealed to be the mall's manager, Mr. Taylor. This is the disturbance at the mall that Dangerous Dan has been mentioning through his broadcast.
