Critics and viewers alike praised the first series for its twisty plotting—often compared to Line of Duty—and Rundle’s standout performance as a relatable yet steely detective navigating moral grey areas. Series two promises to escalate the stakes, with Jo’s promotion bringing new responsibilities while old threats, including the corrupt Sergeant Phil Mackie (Nicholas Gleaves), loom large. Mackie’s blackmail from the previous season threatens to destroy Jo’s family reputation, forcing her to balance duty with protection of her loved ones.
