本片为英剧《军情五处》电影版，也是这一系列剧的大结局。讲述了恐怖分子卡西姆在押送过程中逃跑，MI5的情报长官皮尔斯随后失踪，被怀疑叛变，其门徒威尔被组织任命查出真相。

The eighth season of the British spy series "MI-5," which follows secret agents as they foil evil plots around the globe, begins with the fallout from Harry's kidnapping by the Russians. A mysterious organization known only as "Nightingale" is the ongoing focus of the eight episodes. And Lucas' relationship with CIA agent Sarah Caulfied (Genevieve O'Reilly), reignites concerns over his loyalty. This season also sees the exit of one of the few original cast members, Malcolm Wynn-Jones.

The tenth and final season of long-running British espionage thriller "MI-5" sees Harry return to his post as head of Section D, wherein his Russian opposite Ilya Gavrik (Jonathan Hyde) proposes a strategic partnership between their countries. New "spooks" Erin Watts (Lara Pulver) and Calum Reed (Geoffrey Streatfield) join the fight to prevent all enemies of the alliance from sabotaging the plan and instigating a war.

这是一部英国版的《24小时》，不过显然军情五处的特工们没有杰克那样丰富多彩惊心魂的生活。本剧集是在“911"背景下，描述中东恐怖分子目标已指向英国，他们要爆炸英国的发电站及一些重要的建筑物。此时军情五处的特工汤姆、丹尼、乔伊接到命令要阻止这群恐怖分子的行动。三位特工为了完成任务，掩饰自己的真实身份进行秘密调查，他们将面临什么样的困难呢？

Season seven of British spy thriller "MI-5" opens with Adam Carter (Rupert Penry-Jones) valiantly battling to move a car bomb away from a densely packed memorial service. Meanwhile Harry secures the release of Lucas North (Richard Armitage), a MI-5 officer imprisoned in Russia for eight years. It's not long, however, before Ros begins to suspect Lucas' loyalties. The rest of the season deals with a top secret Cold War-era operation named Sugarhorse.

Season nine of long-running British spy thriller "MI-5" opens with Ros' (Hermione Norris) funeral, where Harry (Peter Firth) learns of a shock…

In the fifth season of the British espionage thriller, Harry Pearce and Adam Carter begin to suspect that members of the British establishment are creating a crisis in order to bring about a change of government. In the opening episodes Juliet Shaw encounters a car bomb, and her life is changed forever. Plus we meet former MI-5, turned MI-6 officer Ros Myers (Hermione Norris), who discovers a shocking family connection to the season's game-changing conspiracy.

The British espionage drama "MI-5", provides more shocking twists and turns in its third season. Tom Quinn (Matthew Macfayden) disappears following a shooting and new man Adam Carter (Rupert Penry-Jones) rises to the challenge in Section B. After recovering from his injury, Harry (Peter Firth) tasks Adam with proving Tom's innocence. Later in the season Danny (David Oyelowo) and Zoe (Keeley Hawes) are sent on a mission that has tragic consequences for one of them.

The stakes are raised in season two of "MI-5", as the threat to national security increases and the need to thwart the terrorists operating within the UK becomes more urgent. Tom is investigating a Serbian terrorist plot. His girlfriend and her daughter are trapped in Tom's house with a lap-top which is thought to contain a bomb. Meanwhile another bomb is primed to explode and this one kills the Secretary of State for Northern Ireland. Adding to the possible dangers faced by other government officials, Tom learns from his American colleague that an assassin is in town, the CIA know about him but they haven't told MI-5.

In season six of the British espionage thriller, the team are pushed to their limits, as the relationship between British and American security deteriorates and loyalties change. Adam and Ros fight against an emerging terrorist threat, and a deadly virus that could decimate London. This season breaks away from the case-by-case episodic format, with one dominant storyline tying all the action together.
