The fact-based crime drama begins with Samantha Stobbart striking up a new romance, but she is increasingly nervous about her abusive ex-partner Raoul Moat - who is about to be released from prison.
After his attack on PC David Rathband has terrible consequences, Moat continues to evade capture and doubles down on his threats against the police. Senior officers try to manage the manhunt amid reports his prison release was mishandled.
The manhunt focuses on the village of Rothbury. The press attention is antagonising Moat, prompting police to request a media blackout. The police enlist the help of a survival expert, but a fresh sighting makes another attack seem likely.
