It's 1989, and Jim Daley is now a fully-fledged detective constable, working in the heart of Glasgow. When ruthless gangster James Machie's accountant, known as the Magician, is found stabbed to death in a multi-storey car park it's clear all is not well within Machie's organisation.

Meanwhile Daley's friend and colleague DC Brian Scott has been having some problems of his own. To save his job, Scott is persuaded to revisit his past in an attempt to uncover the identity of a corrupt police officer. But there's a problem. To do so, he must confront Machie and his cohorts. Brian Scott is soon embroiled in a deadly game of cat and mouse with his childhood friends.

As Daley seeks out his old mentor, Ian Burns, to help save his friend and find out who is telling the truth, it becomes a desperate race against time.
