From his final fall, recorded on CCTV outside a storage lock-up in suburban Sydney, Blue Murder: Killer Cop tracks back to Kings Cross, 1989. On the eve of a new decade, ‘disgraced former detective’ Roger Rogerson (Richard Roxburgh) struggles to find relevance in a rapidly changing world. With the old guard of corrupt Kings Cross detectives soon to be taken down by authorities, can Roger fight to get back in the game through his connections? Or will new found love with Anne (Toni Collette) inspire him to take a new path?

Roger Rogerson (Richard Roxburgh) looks to make ends meet by proposing a scheme to his good mate “Mickel” (Dan Wyllie). But Mickel faces personal challenges of his own, not least in the form of crusading NSW Crime Commission Investigator Mark Standen (Matt Nable) who has plans to pursue Mickel to his last breath. Can Roger succeed in his plans and help his mate too?
