Strike Back: Season 1

John Porter leads his unit into battle trying to rescue the CEO of a British weapons manufacturing company captured in Iraq, just before the invasion started. His team is joined by Hugh Collinson, operative of British military intelligence. The operation almost goes awry when Collinson kills larger portion of Porter's team, and blames a teenage suicide bomber, As'ad, Porter previously saved. The surviving members of the team manage to rescue their target, and Porter rejects Collinson's offer to joint Section 20, a new unit within military intelligence, doubting Collinson's account of the rescue operation incident and resigns from the SAS.

Seven years after the events of part one, Porter is reactivated and tasked with rescuing a kidnapped reporter Katie Dartmouth. Porter realizes that Katie was kidnapped by the same terrorists he fought seven years before, including that teenager, now a young man. He succeeds in saving Katie's life, but fails to rescue As'ad after Collinson orders the rescue helicopter crew not to allow the rescue of As'ad. Just before the helicopter arrives, As'ad tells porter that Collinson killed those soldiers and covered it up by blaming him.

A sniper attempts to kill the President of Zimbabwe. Since there is evidence that the sniper could be British, Porter is sent in undercover to locate the sniper and silence him.

Collinson travels to South Africa to confront the contact who betrayed section 20, but finds it may be too late; while Colonel Tshuma launches a manhunt to find Porter and Masuku.

Porter is sent to Afghanistan to find a computer hacker who has cracked the British army's missile guidance codes. The hacker has successfully found a way to redirect missiles to strike American forces.
