Meadows enlists the help of former colleague Webb when rapist Martin Delaney escapes from prison. Webb begins by questioning a prostitute whom Delaney attacked shortly after absconding, but begins to suspect that Delaney's motives for escaping are much less clear cut than he expected, when the pair come face to face – but Delaney ignores the chance to exact his revenge. Meanwhile, Barratt decides to spend a day out on the beat with Casper, and the pair investigate an armed robbery at a money transfer shop. However, seizing his chance, Barratt confronts Casper about his affair with his wife – but the situation comes to an ugly head during a sting to catch the robbers red handed.
