Just because the most dangerous criminals in society are caught and locked up, doesn't mean they stop committing crime. That's where Kennedy Allardyce comes in - monitoring not just the prisoners, but also the staff. And she's just stumbled across her most dangerous foe yet - rumours of a corrupt guard with lethal influence. And what's worst, it seems they've already realised Kennedy is on their tail. At least one thing is giving her joy - a blossoming relationship with Molly, a beautiful, enigmatic new guard. Wouldn't it be awful if the killer she's hunting turned out to be the woman she's falling for?
