Jo and Suzie investigate when a young boy is attacked in an area known to be frequented by rent boys. Arresting their prime suspect proves to be the catalyst for a much bigger problem, when suspect Ravi Shah accuses DAC Roy Pearson of being part of a paedophile ring. However, when Suzie organises a raid on the home of known pimp Julian Hargreaves, she fails to uncover any proof of his involvement. Meanwhile, Ramani interviews Abi over her accusations against Hugh and a search of a previously undiscovered flat belonging to Hugh reveals vital evidence to prove his involvement, and suspect Greg Campbell is charged with the murder of Karen Burnett.
