Moscow after nuclear strikes. The surface is contaminated, and the city lies in ruins. Survivors have gathered in underground shelters, but resources are running out. The only chance is the old collectors and service tunnels—known by only a few.

No heroics and no extra drama. The everyday lives of those for whom the subway has become the only home.
