It's Christmas Eve and Tori just wants to get drunk and party, but when a robotic Santa Claus at a nearby toy store goes haywire and begins a rampant killing spree through her small town, she's forced into a battle for survival.
After ditching her Tinder date on Christmas Eve, record store owner Tori finds herself stuck with her employee Robbie for the night. But the night is still young. When the co-workers visit some friends in the neighbourhood, bent on binge-drinking and having fun, instead, they cross paths with Robo-Santa: an animatronic, military-grade killing machine. And as the malfunctioning unit embarks on a rampant killing spree in the town's snow-covered streets, Tori and Robbie must face a bloody battle against the odds and the electronic, axe-wielding Father Christmas. Now, a murderous Santa is on the loose, and everyone is on his naughty list. Who can stop the cold, brutal killer?—Nick Riganas
Fter closing up her Placerville record shop for the night, Tori and her employee Robbie visit their friend Lahna and her boyfriend Jay at a nearby novelty store, which displays a recently recalled animatronic RoboSanta+ built with military-grade technology. The four friends briefly drink whiskey together before Tori and Robbie leave for the local bar. As Lahna and Jay start having sex in the store, the Santa robot malfunctions and becomes a homicidal stalker that kills them.
Following a trip to the bar where they have an awkward encounter with Sheriff Monroe, Robbie drives Tori back to her place for more drinking and oral sex. The Santa robot follows them.
Santa murders a mother and father in the house next door to Tori's. From her kitchen window, Tori sees Santa kill the couple's young child. Tori screams for Robbie to call the cops.
Tori wakes her visiting sister Liddy and Liddy's husband Mike to warn them about the killer Santa. Santa cuts the house's power and breaks down the front door. Santa twists Liddy's neck and then kills Mike with the fire ax he took from the store.
Tori and Robbie flee outside to Robbie's car. In his hurry to start the troublesome engine and escape, Robbie hits a vehicle belonging to Tori's neighbor Benny. Benny storms outside of his house to angrily confront Robbie only to be killed by Santa.
Santa swings his ax into Robbie's face just as Officer Davies arrives in response to the 911 call. Davies seemingly fells Santa with his shotgun, but Santa eventually recovers the weapon and uses it to shoot Davies.
Tori drives the officer's patrol car into and then over Santa, but the robot survives. On her drive away from the scene, Tori flags down additional cops responding to the 911 call only to end up arrested by Officer Bobby Smith.
Smith escorts Tori back to the police station where Sheriff Monroe also has difficulty believing her story about a killer Santa. An ambulance suddenly explodes outside as Santa creates a commotion that allows it to kill Monroe and Smith.
Tori eventually escapes the station in an ambulance with Santa climbing his way toward the passenger seat. Tori intentionally crashes to jettison Santa through the windshield. She then starts a fire that causes the robot to explode.
Tori takes refuge in her record store. Now mostly a metal skeleton, Santa reanimates and continues his pursuit. A protracted battle inside the store finally ends with Santa's circuitry overloading and Tori exiting to the sunrise outside.
