In a big American city, the serial killer The Picasso Killer is terrorizing the dwellers and the police department does not have lead to find him. The bartender Christie Wallace dreams on moving to the countryside with her six year-old daughter Zoe to have a peaceful life far from the violence of the city. Late night of Christmas Eve, Christie leaves the Tides Bar where she works and walks back home. In an alley, she sees a woman dying covered on blood and The Picasso Killer sees Christie and chases her. She runs to a commercial building where the night watchman Wade is reluctant to open the door and does not give credit to Christie. She calls the police and Detectives Stefan Kerchek and Lawrence Kellog attend the call. When Christie tells that she can recognize the infamous serial-killer, there is a blackout, the phones are dead and the detectives cannot call the precinct. They lock the building waiting for reinforcement but sooner they find that The Picasso Killer has broken in the building and their lives are in danger.
