Philip Glenister takes the role of Prison Officer David Murdoch whose life becomes complicated when on a routine visit to a Manchester hospital with female prisoner Jules Hope (MyAnna Buring) events spiral out of control. David takes a phone call, which will change his life forever, and he suddenly finds him on the wrong side of the law.

With the life of his heavily pregnant daughter, Lucy (Sammy Winward), threatened, David has no alternative but to go on the run and inadvertently becomes the prey. Unaware of the danger to Emma, DS Susan Reinhardt, whose personal happiness seems forever blighted, tries to unravel why David is suddenly behaving totally out of character. With his reputation as a prison officer intact, Reinhardt attempts to unravel why he makes every effort to strenuously dodge the Police."
