Rookie cop Rachel is about to begin her first night-shift in a neglected police station in a Scottish backwater town--the kind of place where the tide has gone out and stranded a motley bunch of the aimless, the forgotten, the bitter-and-twisted who all think that they really deserve to be somewhere else. They all think they're there by accident and that, with a little luck, life will get better. Wrong on both counts. Six is about to arrive--and all hell will break loose.
