Two shocking and unexpected murders shatter an already fractured Nottinghamshire community leading to one of the largest manhunts in British history. Suspicion is rife and the tragic murders threaten to inflame historic divisions sparked during the Miners Strike that tore families apart three decades before. To solve the murders, police inspectors Ian St Clair (David Morrisey), and Kevin Salisbury (Robert Glenister), must reunite and bury a rivalry that stretches back to 1984, to heal wounds, and catch a killer. But can a community repair itself as more is discovered about those who live there, and whether they really are who they say they are?
