At dawn, a man wakes shivering in an upgraded RV as a brutal cold snap blankets the city in snow and plunges temperatures to deadly lows. He watches emergency broadcasts warning of extreme weather and zombie sightings, urging everyone to stay indoors. Despite the chaos outside, he remains safe in the suburbs, recalling past struggles with cold but now enjoying warmth and comfort. His routine is disrupted when a deceitful coworker repeatedly contacts him via texts and video calls, pushing him toward an uneasy confrontation as the blizzard shows no sign of easing.
