As it becomes clear that someone wants June Ackland dead, she is horrified to find CID digging through her painful past to discover the killer's identity. Tired of being holed up in a safe house, Ackland decides to go back on duty, as this may also draw the killer out of hiding. There is a close shave when she is seperated from Sgt Cryer on street patrol and a man pulls an imitation gun on her, although she is rescued by a covert SO1 officer. Meanwhile, a witness to the arson on Ackland's flat, Mrs Cooper, comes into the station to make a statement.

While speaking to Ackland and Loxton about the problem of local dog mess, a woman is shot dead by a sniper. Meadows and his CID team are tasked to investigate, and suspect that the woman was not the intended target, and it is strongly possible the sniper was after Loxton, who is set to testify in court against an attempted murderer that afternoon. However, when Ackland's house is set alight that night, CID come to the conclusion that she is the intended target. Writing up a list of possible suspects, Ackland gets sucked into a deadly cat-and-mouse game to try to draw the killer out - resulting in the death of one of Sun Hill's best officers.
