The city of Birmingham, Alabama, is experiencing a massive blackout. Planes suddenly lose power and crash to the earth. Cars stall in the middle of the street and won't restart.

Hoard their possessions to survive—or trust God to provide as they share their resources and hearts with those around them? Yesterday's world is gone and now all they've got is family and community. Like never before, they must rely on each other.

Especially since someone close by is a killer.
