The Barnes family is in trouble. Dickie's car business is going under, but instead of doing anything about it, he's out in the woods preparing for the actual end of the world. Meanwhile his wife Imelda is selling off her jewellery on eBay and half-heartedly dodging the attentions of fast-talking local wrongun Big Mike. Their teenage daughter Cass, usually top of her class, seems determined to drink her way through the whole thing. And twelve year old PJ is spending more and more time on video game forums, where he's met a friendly boy named Ethan who never turns his camera on and wants PJ to run away from home.
