Ray, Claire and their seven-year-old daughter Zoe are an ordinary American family living in Kingsville, North Carolina - except they've been living in a bomb shelter since the world ended. For 301 days, they've turned the concrete dungeon into a home, clinging to memories of the past and hoping to someday return to normalcy. For 301 days they have managed to avoid what dwells on the surface - heavy breathing and rumbling footsteps in the night.
