Boulton and Skase get a major lead from an informant on local armed robber Anthony Payne, who has been off the radar for a number of years. Boulton is determined to nail him, but the rest of CID think he's being excessive in his approach due to Daly being named Acting DI ahead of him in Deakin's absence. The raid nearly goes perfect, but Payne escapes and attacks Boulton while he's in pursuit. Skase ends up split up from his DS, and when he catches up to him, Boulton is pulling Payne's lifeless body out of a creek. After CPR fails, CIB are called in to investigate the death in custody. Rumours and speculation are rife, and Boulton's approach with CIB leads to a reprimand about his attitude ahead of an inquest. His day only gets worse when his informant turns against him after being bought by Payne's brother. Can the rogue DS survive with his career intact?
