All 16 episodes from the first and second series of the action drama based on the novel by former Special Forces operative Chris Ryan. The first series follows ex-SAS Sergeant John Porter (Richard Armitage) and MI6 officer Hugh Collinson (Andrew Lincoln) seven years after they participated in an operation in which two soldiers were killed. Porter is redrafted to save a British journalist who has been abducted, the Zimbabwe government holds the UK responsible for a plot to kill President Mugabe and a computer hacker kills a number of American troops. The second series (known as 'Project Dawn') follows the efforts of Section 20 agents Michael Stonebridge (Philip Winchester) and Damien Scott (Sullivan Stapleton), as they try to put an end to an international terrorist group after Porter is kidnapped.
