Malcolm Fox is a cop in Edinburgh, Scotland. He's a member of the Complaints, the ones who watch the rest of the force and bring them to task if they break any rules. Unfortunately, this means he's not very popular among his fellow cops. Add to that a former drinking problem, a sister with an abusive boyfriend, and guilt over putting his dad in a nursing home and you've got a classic cop-with-problems story.
Only this isn't a standard-issue crime drama. When he's between cases Malcolm is asked to look into another officer. This is fine and dandy until his sister's boyfriend is murdered and the cop he's watching, Jamie Breck, is one of the officers on the case. Despite the ethical dilemma, he finds himself becoming friendly with Breck. And soon Malcolm discovers that Breck isn't the only one being watched.
What does a cop do when he finds himself on the wrong side of the law?
