Early one Christmas morning, in a small town deep in rural Australia, Graeme Sweetapple is heading home with a truck full of stolen steers when he comes across an upended ute that has hit a tree. He is about to get involved with Luke, an environmental protestor who isn't what he seems; a washed-up local politician, Caroline Statham, who is searching for a sense of purpose, but whose businessman husband seems to be sliding into corruption; and Carson, who is wild, bound to no one, and determined to escape her circumstances.
Into their midst comes Retribution, a legendary horse worth a fortune. Her disappearance triggers a cycle of violence and retaliation that threatens the whole community. As tensions build, they must answer one question: is true retribution ever possible - or even desirable?
