Eager to justify Commissioner Miller?s (James Nesbitt) faith in her, Liz (Brit Marling) presents her vision for Metwork: the force?s very own digital news channel that will rival established outlets and tell it like it is, for better or worse. It could be a game-changer but to Finn (Bertie Carvel) Metwork is a vanity project and he is determined to kill it. His opportunity comes on the eve of the Mayor?s Conference on Policing. With another clash with Deputy Mayor Grant Delgado (Ralph Brown) on the cards, a youth arrested for possession of drugs turns out to be Delgado?s son. Finn leaks the news to trump Liz?s big idea and ruin Delgado in the process. An indignant Liz (Brit Marling) helps Delgado save face unaware that she has rescued Miller?s most powerful enemy. Warwick?s psychological state reaches crisis point after the high-risk pursuit of a gang of armed robbers and firearms trainee Robbie (Adam Deacon) realises he must sharpen up if he is to make the cut?.
