The annual Christmas holiday is finally here. At the carnival party, investment company employee David (Brian Geraghty) finally mustered up the courage to talk to the beautiful female employee Emily (Alice Eve) who had just resigned. Halfway through the party, the two drove back with their friend Corey (Josh Peck). It was almost late at night. Three people who wanted to buy something to eat entered an ATM service station to withdraw money, but when they were about to go out, they found a mysterious and gloomy figure standing outside. The latter killed a strange homeless man in full view of the public. David and others were trapped in a small space. The seemingly random attacks seemed to be under the control of the mysterious man. Can they finally escape? Or become victims of terrorists?
