James Marshall is a successful defence attorney, close to making partner at his firm, having never lost a case.

He enjoys the spoils of success, but his ambitions and his work have destroyed his marriage. Since this breakdown, he has struggled to balance his life, scarcely seeing his young children, but his parents remain a solid support in his life, and his passion for his work has kept him going.

Through his work, he thought he'd seen the worst that humanity had to offer, until the day a vengeful former client attacks his parents.

Terrified for his family, Marshall finds himself making a list of the worst people he's defended, guilty people he had successfully kept out of prison, before tracking each of them down, intent on finding the culprit.
