Six months into the zombie apocalypse, in the dead of winter, you lead your group southward, fleeing the cold weather. As a terrible snowstorm breaks out, your group of three vehicles moves slowly along the hazardous highway, and your fuel is dangerously low.
As the storm turns into a whiteout, a cabin appears in the distance. Smoke comes from the chimney, and you can see the cabin is large enough to support your group of 10.
As you pull into the driveway, an older man appears in the doorway, flanked by a younger man, likely his son. He opens the door slightly, showing the barrel of a shotgun and shouts, "We have no room! Keep moving!"
Your people are exhausted, cold, and the vehicles can't go much further without refueling. The snowstorm is only intensifying, reducing visibility to near zero.
