The Barnes family is in trouble. Dickie’s once-lucrative car business is going under but Dickie is spending his days in the woods, building an apocalypse-proof bunker with a renegade handyman. His wife, Imelda, is selling off her jewelry on eBay and half-heartedly dodging the attention of fast-talking cattle farmer Big Mike, while their teenage daughter, Cass, formerly top of her class, seems determined to binge drink her way through her final exams. As for twelve-year-old PJ, he’s on the brink of running away.
