Plot

When a terrorist escapes custody during a routine handover, Will Holloway must team with disgraced MI5 Intelligence Chief Harry Pearce to track him down before an imminent terrorist attack on London.

MI5 personnel are caught up in a traffic jam in London while escorting the CIA's most wanted terrorist to an arranged CIA handover point, when he is suddenly rescued by armed men on motorbikes. Harry Pearce, the head of Counter-Terrorism at MI5 is blamed for the terrorist escaping. Especially as Harry disappeared shortly after the incident. An ex-agent, Will Holloway, and protégé of Harry's is recalled by MI5 to assist in finding and bringing Harry in. However Harry has disappeared for a reason. Certain that there is a traitor in a senior position in MI5, he enlists the somewhat reluctant Will to help him in uncovering the rat or rats concerned.—Woodland Outlaw

Jihadist terrorist Adem Qasim was to be delivered to the CIA by MI5 convoy, but klutz June Keaton's supervisor gets shot when she gives chase against orders after perfectly organized motor-bikers take enough hostages to convince counter terrorism chief Harry Pearce to accept an impromptu exchange, realizing that costs him his job. Seeking to settle that score, Harry tricks Will Holloway, the son of his Berlin-killed best agent, whom he fired dubiously but whom the brass now made return from his dangerous new career in the Moscow underworld to trap Harry, to 'defect' with him. Although not amused, Will accepts, promised the truth about his ever-absent father's end, to look for a mole, who proves dangerous enough covering his tracks, and take on Qasem while testing Harry's theory that the secret agenda was not just his downfall but the end of MI5, to be reduced to a CIA appendage. Harry strikes a risky deal with Qasem, which requires working with the Russian FSB.—KGF Vissers

In London, while transporting the CIA's most wanted terrorist Adem Qasim to handover to CIA personnel, the MI5 team is trapped in a traffic jam and is forced to deliver the terrorist to a group of armed men on motorcycles. The Chief of the Operations, Harry Pearce, is blamed for the fleeing and vanishes immediately after simulating a suicide. The MI5 summons the former agent Will Holloway to help the agency to capture Harry, since his father and him worked with Harry. Soon Will meets Harry and learns that there is a traitor in the direction of the MI5 and invites Will to work with him. But Will is not sure whether Harry is telling the truth. Meanwhile the terrorist Qasim is threatening to blow-up locations in London unknown by the MI5.—Claudio Carvalho, Rio de Janeiro, Brazil

After an extremely dangerous terrorist escapes from MI-5 custody, Harry Pearce disappears, making it look as though he might have had something to do with it. MI-5 looks to Will Holloway, an ex-agent who trained under Pearce, to head into the field in order to bring him in. However, Pearce tells Holloway that he is only hiding because he is certain that someone high up within MI-5 is the one behind it, and eventually is able to convince Holloway to work alongside him to bring justice. Throughout the movie, these two are on the run from MI-5, looking for their lost terrorist, as well as trying to find out who the leak is inside of the agency. There are many different, albeit small, plotlines to follow, but they come together to make a good film that keeps you engaged. While on the run from the agents at MI-5, Holloway has a run in with one of the ones involved in the prisoner transport. He trusts her in order to find out who the mole is within MI-5, but later is betrayed by her, although he makes it through that situation. However, she says that she was simply following orders, but won't admit who the one giving them was. Still running, Pearce ends up getting in touch with the terrorist that escaped, and wants to meet with him for the purpose of stopping his bombing plans and recapturing him. The terrorist is only willing to meet if Pearce can get his pregnant wife out of another agency's custody and reunite the two of them, to which Pearce agrees. Another speed bump comes when he retrieves his wife, but she and the child are already dead, causing Pearce and Holloway to think of a new plan. They call one of the MI-5 agents chasing them, and ask if she is able to help out by posing as the terrorist's wife, as they are to meet on a public bridge.They do this, and the terrorist has one of his men shoot the women from a rooftop, knowing it was not his wife. Unbeknownst to the viewers, Pearce makes a deal with the terrorist to give up the location of all the bomb equipment, and MI-6 seizes it all, and Pearce and Holloway end up back at headquarters. While there, the terrorist makes his way inside the building, seeming to know all the passwords, locations of keys, and anything else needed to make their way through secure areas. Pearce is asked what he gave him in order to get him to give over the bomb materials, and he replies, "I gave them you," directing attention to the 'man in charge.' Holloway and the woman who betrayed him earlier ended up killing the rest of the terrorists, and Holloway ended up getting a clear shot to the main terrorist, killing him, and ending the major plot of the movie. Pearce sacrificed a few lives of some of the security, as well as giving the terrorists the corrupt leader in their midst, in order to prevent public loss on a much larger scale. Holloway was not a fan of his recklessness in terms of caring for the lives of innocent people, but in the end, understood that many lives were saved. From there, it flashes to a bit of a brighter future, where Holloway is being asked to join MI-5 for his outstanding courage, and his tremendous ability in taking down the terrorists. Pearce was originally thought to have sabotaged Holloways first attempt at joining the agency, and finally admits that he did it because Holloway's father lost his life fighting for them, and he didn't want that for his son as well. Pearce and Holloway now work together as a part of MI-5, and work to protect Britain from any future threats that might come their way.
