  • On Christmas Eve, an escaped maniac returns to his childhood home, which is now a sorority house, and begins to murder the sorority sisters one by one.

  • In the 70's, the boy Billy is born with yellow skin due to a liver disease and his dysfunctional mother rejects him. Later he witnesses his mother and her lover killing his beloved father and burying him in the basement of their house, and he is locked in the attic alone along his childhood. When he is a teenager, he is sexually abused by his mother and she has a baby girl called Agnes. During Christmas, the deranged Billy escapes from his imprisonment, kills his mother and stepfather and blinds one eye of Agnes. He is declared insane and his sister is sent to an orphanage. In the present days, Billy escapes from the Clark Sanatorium to spend Christmas with his family. Meanwhile, his former house is the Delta Alpha Kappa sorority house in the campus of the Clement University, and the housemother and the sisters Kelli Presley, Dana, Lauren Hannon, Megan, Heather, Megan Helms, Melissa and Eve Agnew are preparing the house for Christmas party in a stormy night while Clair Crosby is in her room writing a card to bury the hatchet with her sister. When three sisters vanish, the others receive weird phone calls and believe something is wrong, but they find that they are trapped in the location.

  • The movie tells the story about Billy, a young boy who was abused by his mother as a child. While his mother was cheating on Billy's father, she eventually killed his father and kept Billy in the attic - for good, while she was with her lover and starting a "new" family. As Billy's mother fell pregnant with a daughter and treated her with love, which Billy had never experienced with his mother, Billy came out of the attic after years and brutally murdered his mother and her lover. Cut to present day, a group of eight sorority sisters consisting of Kelli, Dana, Lauren, Megan, Claire, Heather, Megan and Melissa and their house mother, who now live in Billy's childhood home, find themselves being harassed by threatening and intimidating mystery phone-calls during Christmas Break and as one of the girls goes missing, the girls begin being murdered one by one by no other than Billy...

  • Not all Christmas stories are full of cheer - take the disturbing childhood of Billy Lenz, for example. Born during Christmas, little Billy Lenz suffered from Jaundice because of a liver defect, and was unwanted by his cruel mother (who only saw the husband she'd come to despise when she looked at her son). While she let her true feelings be known to him with beatings and abuse, only his father showed him compassion like a parent should. But on Christmas Eve in 1975, his unfaithful mother gave him one of the most cruelest gifts of all, as she made five-year-old Billy observe his beloved father's brutal murder at her own hands and those of her lover with a claw hammer. Before burying him under the house, she locked Billy in the attic for good, to hold his silence of what he'd witnessed that night. His only contact from then on was when she came to punish him for making a noise or other such trivial nuisances, while she was with her lover and starting a "new" family. As Billy's mother fell pregnant with a daughter and treated her with love, which Billy had never experienced with his mother, Billy came out of the attic on Christmas Eve 1991, taking a rolling pin to his mother's head, and a pointed tree ornament to her lovers eye before leaving his sister as disfigured as he was by blinding her. Before he could finish the job police forced there way in and dragged him off to mental institution and his sister a foster home, whose eye sight was saved in one eye... but not the other. Cut to the present where a security guard has been monitoring Billy's progress since he came into his care, back in 1991. Knowing full well that during this time for fifteen years, Billy has made a break from this asylum, but never succeeding... until now. Far away, his childhood home is now a sorority house, where nine sisters and their house-mother are celebrating the holiday season together ...but tonight they're about to get a surprise visitor... and it's not Santa.


The synopsis below may give away important plot points.


  • On a snowy winter night on Christmas Eve, in the Alpha Kappa Gamma sorority house, Lauren (Yan-Kay Crystal Lowe) is getting changed into her pajamas. In the next room Clair Crosby (Leela Savasta) is writing a Christmas card to her half-sister, Leigh (Kristen Cloke). Suddenly she hears something from her closet. She goes over to the closet door and looks inside. Nothing but clothes. She goes back to her card and sees that her fountain pen is missing. Suddenly a figure wraps a bag around her head. In the struggle, the figure stabs the pen into her eye.

    At a mental institution not far away, Billy Lenz (Robert Mann) is being served his Christmas dinner. He is locked away, rocking back and fourth in his rocking chair, safely in his cell that is decorated with Christmas lights. The orderly serving the food gets a scare from a volunteer dressed as Santa who is looking for the children's ward. Security guard J. Bailey (Ron Selmour) makes jokes to the orderly about Billy trying to escape every year. The orderly and Santa walk away, leaving the security guard alone in the hall. Billy opens the small window on his cell and places a present wrapped in newspaper on the ledge for the security guard. The security guard opens it to find nothing that interesting, except on the newspaper is written "I'll be home for Christmas." The security guard looks into the cell to find it empty and Billy's chair rocking back and fourth. He quickly opens the cell and goes inside, to find a hole in the wall. He takes his flashlight and looks into the hole, as Billy comes from under the bed and stabs him in the neck with a candy cane. Billy leaves the cell and kills the man dressed as Santa. He steals his outfit, stuffs his body in a bag, and leaves the institution, dumping the bag in the dumpster with the man's hand sticking out from the bag.

    Outside of the sorority house, Kelli Presley (Katie Cassidy) and her boyfriend Kyle Autry (Oliver Hudson) are talking in his car. She tells him that she is going to spend Christmas with her roommates but that she will make it up to him. He is disappointed because this is their first Christmas together. She kisses him goodbye and goes inside the house. As she does her fellow sorority sister Megan Helms (Jessica Harmon) calls Kyle on his cell phone. Meanwhile, Megan is in her room, watching an old home made porn movie that features her and Kyle. Kyle hangs up the phone. Kelli goes inside and greets everyone, including Melissa Kitt (Michelle Trachtenberg), her best friend. Heather Fitzgerald (Mary Elizabeth Winstead), Dana Mathis (Lacey Chabert), Lauren Hannon and Ms. MacHenry (Andrea Martin), the house mother who loves all of the girls and accepts their flaws.

    They have a "secret Santa" gift giving thing going and Ms. Mac wants to know who got Billy. According to her, Billy (Cainan Wiebe) killed his family here. When Billy was born, he has a liver disorder that makes his skin yellow. His father loves him regardless but his mother is disappointed and wants nothing to do with him. They live in the house that is now the sorority house. As Billy gets a bit older he is treated even worse by his mother, who has become an alcoholic. On Christmas, when he is five, his mother tells him Santa was shot down by the Russians. His father, however, tells him he has a present for him hidden in a stow-away space in Billy's closet. Billy goes into his room, which will become Eve's in the present day, and finds a telescope, making him briefly very happy. However his mother and father are not getting along very well, and his mom is having an affair. Moments after finding the telescope, Billy hears arguing and looks under the door to witness his father with a bag over his head and his head being bashed in with a hammer. Billy runs back to his room as his mother and her lover take the body outside and begin to bury it in the crawl space under the house. Billy is watching this and is discovered. His mother chases him into the attic and locks him in there.

    All of the girls are horrified by this story but Ms. Mac assures them it is all true. Heather says she was the one who drew Billy's name for secret Santa but she thought it was wrong to buy him a gift because he was a murderer and it was offensive to the birth of Jesus to make a mockery of gift giving. Heather starts to go upstairs to her room but runs into Eve Agnew (Kathleen Kole). Eve has been upstairs the whole time and is leaving to go visit her family. She gives Heather her secret Santa gift, a crystal statue of a unicorn. Heather is less than impressed and bids Eve farewell. Eve goes towards the door but Ms. Mac tells her she has a present for her. Before she can find it, Eve leaves, obviously disappointed by Heather's reaction.

    Kelli and Lauren go upstairs to tell Clair and Megan they are going to open the presents. Clair obviously doesn't answer. Lauren pounds on the door and says she is going to steal her presents if she doesn't get down here. Laughing, Kelli does this on Megan's door. Megan tells them to go away and she doesn't want to open presents. They leave and Megan hears a snow globe tune playing in the attic. She goes into the attic and asks if someone is playing a joke. She gets more then she bargained for when she finds Clair's body by the window in a rocking chair. Someone comes from behind and smashes the snow globe into her head. She falls onto the ground as a bag is put over her head. She fights back, but the figure rips out one of her eyes with their bare hand!

    The home phone rings, Melissa answers it and puts it on loud-speaker. The caller is making all sorts of weird noises. Lauren teases him, and the caller threatens to kill Lauren before hanging up. Heather says someone is obviously sick in the head and doesn't need to be provoked by Lauren. Melissa checks the caller ID and is surprised to see it's coming from Megan's cell. They assure themselves it's just a joke.

    They open their presents, with Ms. Mac getting some lingerie as a gag gift. Everyone laughs and Kelli goes back upstairs to check on the girls. Kyle suddenly pops out of Megan's room. Kelli screams and the other girls rush upstairs. Kyle apologizes and says he wanted to surprise her. Ms. Mac asks if Megan is in her room and Kyle says he doesn't know. Lauren asks him how he could have just been in her room and not know if she is in there. He explains that it's really dark in there. He makes a joke about Billy getting her. He then tells everyone another story about Billy's past.

    Billy was kept in the attic for many years. His mother and stepfather lived happily without him. Everything was wonderful except his mom couldn't get pregnant by his step-father, and was sexually frustrated by his inability to maintain an erection. On Christmas, when Billy was twelve, she crept into the attic and had sex with him, her own son! Nine months later she gave birth to a baby girl named Agnes (Dean Friss). She loves Agnes, and uses the occasion to further reject Billy, looking up to the attic where Billy is kept, and saying in reference to Agnes, "She's my family now." Variants of this line are used repeatedly in the rest of the movie. As Agnes grew older, Billy became jealous. One Christmas, Agnes got a doll for a present. A jealous Billy releases a tantrum and breaks the attic door open and rushes to the living room, attacking Agnes and pulling out one of her eyes, stabbing his stepfather in the face and beating his mom to death with a dough roller. When the police arrive on the scene, they find him eating a cookie made from his mother's flesh. Agnes was put into an orphanage and no one knows where she is today.

    The girls are freaked out by the story. Kelli goes inside Megan's room and finds the porn video on the computer. She breaks down and Kyle tells her it was from a long time ago. Kelli screams for him to leave the house and he becomes enraged, calling the women "spoilt bitches." Ms. Mac goes off on him about treating Kelli like that, pushing him towards the stairs. As Kyle leaves, a figure is standing by the tree looking at the presents. Ms. Mac asks who the person is. Clair's half-sister, Leigh tells the girls that Claire never called her, telling her she was ready to be picked up and she is worried. Dana says she even had no idea Clair had a sister. Leigh explains they are only half-sisters and are trying to get to know each other.

    Suddenly the power goes out in the house. Dana says the circuit breaker is under the house and she will go turn it on. She goes outside and smokes, dropping her cigarette into a hole on the porch. She hears someone underneath it. Taking her flashlight she opens the door to the crawl space and looks inside. Suddenly someone grabs her, pulling her in. The two struggle as the figure grabs a gardening tool and stabs Dana in the head. Lauren is beyond drunk now, having been drinking booze the whole night. Melissa tells her she smells and needs to shower. As she showers, someone watches from a broken tile in the floor. After the shower, Lauren goes to bed.

    Everyone starts asking where the other girls are, since Clair, Megan and Dana have disappeared. Kelli questions what is taking Dana so long, and is even more startled when someone calls from Dana's cell number and hangs up. The rest of the girls go outside to look for Dana. Heather and Leigh find Eve's car still parked outside. They open the car door and scream as Eve's severed head rolls out. The girls scream and run back into the house, locking the door behind them. Kelli calls the police but because of the snow it may take over two hours for them to arrive. Ms. Mac tells everyone that they can pile into her car and try to find help. Kelli says that they won't get far and that they need to stick together. Heather says she wants to leave, and Ms. Mac tells the girls that they can stay and she will go with Heather to find help. The two go outside and get in the car. Ms. Mac gets out of the car to scrape the ice off of the windshield. As she begins to scrape Billy's yellow eye comes into view inside the car. Ms. Mac gasps as he kills Heather, her blood spraying all over the windshield. Ms. Mac falls against the garage door, causing an icicle to fall from above which impales her head.

    Leigh notices that Ms. Mac hasn't left yet. She decides to go see what's going on. Kelli decides to go out with her, leaving Melissa and a sleeping Lauren behind. As they leave the house a figure grabs Heather's unicorn statue and walks down the hall. In the garage, Leigh slips on Ms. Mac's blood and screams. Upon hearing this Melissa rushes towards the stairs. A figure grabs wraps a bag over her head, slamming her into a wall. She rips the bag off and rushes through the house and into her room. She grabs a stick and hits the figure with it. Melissa opens a window and is going to climb out but the figure throws an ice-skate at her, cutting off the back of her head.

    Kelli and Leigh rush inside and call for Melissa. There is no answer and they go to Lauren's room, closing the door behind them. But someone is on the other side of the door and kicks it open. It's Kyle. Leigh attacks him and he throws her against Lauren's bed, causing the covers fall off of Lauren, who is very much dead with her eyes gouged out! Everyone screams and Kyle insists he isn't the killer. Kelli calls Lauren's cell phone and hears it ringing in the attic. She explains that the killer might be in the attic with her phone. Kyle opens the attic door and is pulled inside. Kelli and Leigh try to get into the attic but the door is slams shut. Kyle fights back as a bag is put over his head. Kelli breaks the door open and witnesses Kyle being stabbed with the unicorn statue, then one of his eyes being ripped out and eaten! Leigh attacks the figure and is thrown across the attic, discovering her half-sisters body still in the rocking chair. The figure attacks Kelli and Leigh tries to help but is knocked into a hole in the floor. A bag is put over Kelli's head but she grabs a fork and stabs the figure in the eye. She gets up and sees the figure has a glass eye. It's Agnes. Kelli tells Agnes everything is okay and she doesn't have to do this. She tells him her brother isn't here, he is still locked away. Agnes tells her that she doesn't have a brother, only a father. Billy comes from behind and lights a candle.

    Agnes attacks Kelli but is knocked into another hole in the floor that pins her between the walls! Billy pushes Kelli into the same hole, accidentally knocking over the candle. Kelli has grabbed onto a string of Christmas light attached to a small tree, trying to keep from falling completely in. She screams for help as Agnes starts to crawl up the hole. Leigh comes to her rescue, smashing open the wall. Agnes grabs Leigh's head but she manages to fight her off. Leigh runs through the house and smashes out another wall, finally reaching the spot where Kelli is trapped. Billy is climbing into the hole and Agnes is crawling up it! Leigh grabs Kelli and pulls her to safety as the Christmas tree catches fire (along with the rest of the attic) and falls into the hole, burning Agnes and Billy. The two survivors rush outside.

    At the hospital Kelli is going to have some tests done to make sure she is okay. Leigh has a present in her hand from Clair. She tells Kelli she wants to open it now because she won't be able to open it in front of her family. She says that she is glad she got to know Clair before all of this happened. She opens the present and finds a watch engraved with "Family Forever." She starts to cry as a nurse comes in and tells Kelli they need her for some x-rays.

    Some time later Leigh goes back to Kelli room to see if she is back from the x-rays. A body with blonde hair lays in the bed, but as she approaches the person turns over to reveal Agnes. Leigh screams as Agnes grabs her by the throat and snaps her neck.

    Kelli comes back into the room and feels something is wrong. She finds Leigh's new watch. She sees blood on the ceiling above her and starts to leave the room, but Agnes grabs her from behind the curtain and starts to strangle her. Kelli grabs a defibrillator paddle and shocks Agnes in the head with it, killing her. This is the ending for the UK version. The US version continues from here when Billy comes down from the ceiling, as Kelli rushes from the room. She grabs some crutches that are in the hall and starts to beat him with it. She turns to run, thinking he is unconscious but he grabs her foot, causing her to fall over a medical cart. Billy grabs a scalpel from the pile of medical supplies now on the floor and takes chase. Kelli rushes to the stairs as Billy comes from behind, slashing her with the scalpel. She grabs him and throws him over the stairway, causing him to fall on top of the Christmas tree below, impaling him. His intestines spew out, he is very much dead, and Kelli is left to look on in shock as the credits start...
