14 kids stranded inside a superstore. Inside they have everything they could ever need. There's junk food and clothes, computer games and books, drugs and alcohol - and without adult supervision they can do whatever they want. Sounds like fun? But outside the world is being ripped apart by violent storms and chemicals leaking into the atmosphere that, depending on blood type, leave victims paranoid, violent or dead. The kids must remain inside, forced to create their own community, unsure if they'll ever be able to leave. Can they stop the world they've created inside from self-destructing too?
