Boston Standard journalist Emily - Em - Kelton is desperate for a big story. As a new reporter Em covers the police beat, which has her responding to every crime that comes across the newsroom scanner. Despite the drudgery and the largely nocturnal hours, it's a beat that suits her - especially with her affinity for the low-level criminals she regularly interacts with and what she considers a healthy scepticism for the rules.

But she's sick of filing short news briefs about random street murders that barely merit a byline, and when she sets out to cover yet another shooting of a low-level dealer, she begins to wonder if these crimes are somehow connected.

With not much to go on but her instincts, Em sets out to uncover the truth behind these sordid crimes. But the more she investigates and uncovers a pattern, the more she digs herself into a hole from which she might not come out of alive . . .
