Working with hitman Hugh Rafferty, they begin to take hostages, and the clock is ticking for the team to find them and take down Lyons, or he’ll begin to execute them one by one. Will they rescue the hostages in time, or will they just be another addition to Mad Malkie’s death toll?

There's a killer on the loose, and there's not much time left to stop him. Will Detectives Patrick Knightley and Iain Wainwright, along with PC Terry Gallagher, PC Jon Banes and the Chief be able to catch him - or will he escape?
