2 girls for every boy. Doomsday planners pick the lucky few who will be allowed to take shelter in caves and tunnels. As a huge dirty snowball comet slowly scorches the planets surface, the survivors face a grim new future. With cooperation and luck, they may just survive. Hopefully they've planned for everything. Now they can only wait, and ask themselves, what else could possibly go wrong?
