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
