After a company Christmas party, coworkers David, Emily, and Corey make a late-night stop at an isolated ATM booth. Their routine errand turns into a desperate fight for survival when a mysterious, hooded figure appears outside, trapping them inside the glass kiosk. As the temperature drops and the hooded man begins a sadistic game of cat-and-mouse, the trio realizes they are being stalked by a cold-blooded killer with no clear motive. With their phone service cut off and the exit blocked, they must use their limited resources to outsmart their tormentor before they freeze to death or become his next victims.
