13 May 2002Twenty high-explosive devices are smuggled into England. When the first goes off killing a doctor and severely injuring her young daughter, the team scrambles to track down an American anti-abortion activist who snuck into the country - and may be planning a huge commemoration of her husband's execution back home in just a few days. Things are complicated by CIA insistence that the woman, if found, be extradited back to Florida, where she too will face the death penalty.
20 May 2002Racial tensions in Britain continue to rise and the team pieces together an organized attempt to stir up problems for political gain. Tom and Helen go undercover to get close to the well-protected head of the conspirators. But as time runs short, personal loyalties will leave one team member dead.
27 May 2002Zoe is undercover on a routine op, pretending to be a PR agent hoping to land a contract with the Turkish government. She winds up a hostage - along with dozens of others - when a group of Kurds take over the Turkish embassy and demand the release of political prisoners. However, the team pieces together that this is just a cover, as a disgruntled former spook is using kidnapping and terrorism to gain access to a secret bank account - one with millions of pounds... and the personal identities of every undercover officer.
4 June 2002During riots in advance of US President Bush's visit to London, the MI-5 team observe Peter Salter among the agitators. Salter is a legendary agent and neither Zoe or Danny are quite sure what to do. When they report what they saw to Harry Pearce, he instructs them to remove any reference to Salter from their reports and to forget what they saw. Turns out Harry is running Salter on a special op in cooperation with MI-6. They are trying to nab a well known anarchist who is in the UK to stir up trouble. As the investigation progresses however, Salter's loyalty is called into question. Zoe has another problem when she suspects Tessa of embezzling funds. Tom meanwhile finally has to admit to Ellie what he really does for a living. She doesn't take it all well and she insists that he tell her daughter Maisie the truth or she will leave him.
10 June 2002A former MP, imprisoned years before in an arms-dealing scandal, claims to have a damaging memoir ready to go to press. The team tries to determine whether its claims are genuine while possibly being subverted by other agencies with other agendas.
17 June 2002SPOILERS Patrick McCann, the leader of an Irish splinter group walks into a safe house and insists that he has crucial information for MI5 concerning their investigation on an Middle East terrorist group called Asabiyah. To share in-depth information on Asabiyah's plan to hit a British nuclear power station with MI5, McCann requests that his group goes unwatched for 30 hours. Despite doubts about this collaboration, McCann's splinter group is granted their request of not being watched for 30 hours. It then becomes evident, however, that McCann has planned to release a bomb on one of London's stations which can be repelled by MI5 just in time. In the meantime, things get more serious between Ellie and Tom as she and her daughter Maisie move into Tom's house. When Tom brings his laptop to his home, he realizes too late that it is set up with a bomb and Ellie and Maisie are in great danger.
2 June 2003As Republican nationals make several strikes in London, another bombing at a secret military installation catches the team's eye.

While Tom keeps trying to make things right with Ellie, he and the team race to discover their enemy's final target.
9 June 2003An extremist mullah may be planning England's first suicide bombing. MI5's mole is discovered and tortured, leaving the team in need of someone who can get deep inside the mosque. A former Algerian spy smuggles himself into the UK and offers to help - but his loyalties are questioned by Tom. As the mole gets closer and closer, he falls out of contact with the team, leading to a dramatic showdown in a schoolyard - with one child wearing a bomb.
Season 2, Episode 3: Spiders
16 June 2003Repeated attacks on MI5's computer system threaten the theft of virtually all classified information. Danny is undercover as a journalist for an socialist paper linked to an anarchist group while Zoe takes a turn as a middle school teacher to get close to another instructor who may be spearheading the computer attacks. Moreso than other episodes, though, everything is not as it seems as a long-dead agent and a potential nuclear device at the school play into a web of deceit and confusion that nearly costs MI5 all their secrets.
23 June 2003Twenty billion in US aid has disappeared from Russia. Meanwhile, MI5 is called in to deal with the theft of a billion dollars from a well known bank - that also handles government accounts.

Amid the chaos, the team has to cope with the situation in the midst of a near total communications blackout.
14 July 2003The American president's unexpected visit to London forces the MI5 and CIA teams to work together.

But perhaps JJ can be of use to them in stealing the missile plans.

Tom learns that an American assassin has come to Great Britain. This news was not passed on to MI5. Tom doesn't want to compromise Christine, so he is unable to tell Harry what he knows. On Tom's demand Danny and Zoe - without Harry's knowledge - take on the matter but things turn out badly. Tom's strange behavior and the set-up against Tom make him appear suspicious. Zoe and Danny believe that Tom might have gone bad. No one believes him, so Tom has to flee when he is accused of murder and conspiracy.
11 October 2004After shooting Harry, Tom disappears once again. Evidence clearly speaks against him. Oliver Mace, chairman of Joint Intelligence Committee, seizes the opportunity of the fiasco to take over MI5 and overrule Harry's leadership.

To fill the gap that Tom as a senior officer has left, Adam Carter, an MI6 officer, is recruited by Harry to help out MI5.
18 October 2004The discovery of a nuclear lab in suburban England prompts Harry to activate a long-quiet sleeper agent, a university professor who must sacrifice, albeit temporarily, his name and maybe even his family to trick terrorists into thinking he's created red mercury, a highly efficient chemical detonator. As the op progresses, Tom begins to doubt the wisdom of shaking the sleeper's life to the ground and tries to get the mission scrubbed.
25 October 2004An attack on an Islamic dissident author in his friend's bookstore puts MI-5 on the trail of international terror groups. Danny is assigned to protect the bookseller as Adam thinks he may still be a target. MI-6 isn't being of help and to the point of Adam having to stage an elaborate, hours-long shake of many tails in order to meet with a very highly placed source. In the post 9-11 world, no one is off limits, sides change quickly - and the team certainly isn't being told everything.

Season 3, Episode 8: Celebrity
29 November 2004When the infant child of a fading but recently knighted rock star is kidnapped from his home, the Government wants MI-5 rather than the police to take charge of the investigation.

The security agents determine that a sophisticated laser, used for guiding missiles to their target, is missing from the stash and they are convinced there is a terrorist plot underway. Adam is put in charge of interrogating Morgan and with no more than an estimated 48 hours before the attack, Adam finds himself unable to extract any information using conventional methods. Gradually, he begins to use so-called aggressive techniques bringing into question just how far they are prepared to go to get the information they need. Harry Pearce meanwhile has been short-listed for the soon to be vacant MI-5 Director-General position and prepares for his interview.
13 December 2004After the police raid a house and find evidence that terrorists may be planning an attack in London with Sarin gas, Danny and Fiona Carter, who has now transferred to MI-5 from MI-6, follow up on a lead provided by an informant. It's a trap however and Fiona is soon forced to call husband Adam and under threat of her being killed, is forced to meet one of the terrorists. It's clear that whatever the terrorists are planning, it is related to that day's summit meeting between the British PM and Iraqi and US allies. While Adam tries to find out where Danny and Fiona are being kept, the prisoners are under constant threat with Fiona being threatened with being burned alive for all to see. As the threat increases, one of the two prisoners will not survive.
12 September 2005As the team buries their dead colleague, a bomb goes off in a nearby market. The group, Shining Door, demands the release of their leader Michael Monroe or they will detonate another bomb in 10 hours. The CIA is involved since Shining Door has primarily directed its wrath at the US and Monroe is an American citizen. The group believes that mankind is a parasite destroying the Earth with its technology and believe that it will be destroyed unless humans are dramatically culled. Harry Pierce is less than pleased when a colleague, Juliette Shaw, suddenly re-appears and is appointed to help out given Fiona Carter's absence. She makes sure that what she knows about Harry's past will ensure a meaningful role for her. An ambush where a suspect is shot through the head tells Adam they have a mole in their midst. Their problems are compounded when one of the agents is taken prisoner.
13 September 2005With Zafar Jaffrey being held by the terrorists, Adam Carter had to act quickly to free him but he may have over-stepped when he tries to extract information from one of them. His interrogation confirms his earlier belief that there is a mole leaking information to the group. Harry tells the Home Secretary that he is being blackmailed and therefore submits his resignation. He doesn't mention who is doing the blackmailing, but is up front with the Minister on what he did to compromise himself. Adam is now convinced he knows the mole's identity but accuses the wrong person. MI-5 has an eye witness in Tash, the waitress who bumped one of the terrorists at the train station, and she works with MI-5 to identify the man. Soon however, Tash becomes a target as the mole arranges for some insurance in the event they are captured.
22 September 2005When 6 local Councillors in East London switch their allegiance to the right-wing British Way party, there is fear of race rioting in the area.

At a party rally William Sampson, a Member of Parliament, announces he will now run as a candidate for the new party. Youthful, handsome and articulate Sampson causes concern in the government and with the newly appointed National Security Coordinator, Juliet Shaw. MI-5 plans on causing dissension in the party between Sampson and Keith Moran, another of the party's leaders. When an Afghan asylum seeker is charged with the murder of a young girl, it provides the party with a perfect issue and a powder keg for MI-5.

27 October 2008MI-5 is having a particularly busy day. They have just exchanged spies with the Russians and welcome the return of Lucas North after 7 years of imprisonment. Harry Pierce's Russian counterpart, Arkady Katchimov hints however that they will soon have another agent in custody leading Connie James to try and call off an operation in Moscow that is literally minutes away from happening. Simultaneously, an Al Qaeda splinter group has kidnapped a soldier, Andy Sullivan, who has just returned from a tour of duty in Afghanistan. They release a video threatening to decapitate him if Remembrance Sunday ceremonies aren't canceled. MI-5 learn from the information gathered in Moscow that Al Qaeda is planning a much bigger attack in London.
27 October 2008Convinced that his Russian counterpart in London, Arkady Katchimov, is behind the Al Qaeda bombing that killed Adam Carter, Harry Pearce launches an unauthorized investigation. Their task is to find a non-diplomatic source who would provide then with information on Katchimov's activities. Meanwhile, listeners capture an electronic burst leading them to believe there may be an unidentified Russian submarine in British waters. With Ros Myers now the head of the team, they focus on Alexander Beletsky, a Russian who has a relationship with Katchimov. They conclude that the Russians may be looking to tap undersea communications cables and launch a denial of service attack, thereby disabling the Internet throughout Britain. Lucas North is keen to get back to work but Harry insists that Lucas go through the entire re-integration process before he does so. A good decision given that it appears that North may in fact be working for the Russians.
28 October 2008When a Pakistani agent informs them that there is an Al Qaeda cell planning an attack in London, MI-5 go into action. They already have an agent in place in the terrorist cell which is led by Nadif Abdelrashid. When what is supposed to be dry run turns out to be the real thing, MI-5 track four bombers as they walk through the city to what is their final destination. One by one, MI-5 try to take each of them down before the bombs explode but they aren't entirely successful. Lucas North meanwhile has a flashback to being tortured by his Russian jailers and recalls one of the interrogators asking about an operation known as Sugar Horse. For Harry Pearce alarms bells go off as the operation was one of the most guarded secrets and known only to a very few. He is convinced there is a Russian mole in the senior levels of the intelligence community and turns to Bernard Qualtrough, a retired spy catcher, to help him ferret out the turncoat.
3 November 2008MI-5 is approached by Mohammed Khordad, the number 3 man in Al Qaeda, for a meeting. Under normal circumstances, they wouldn't even think of meeting the leader of a terrorist group but Harry Pearce is convinced that they should look at any opportunity to reduce the threat of attacks. Khordad is keeping his cards close to his chest and insists that they have to trust one another before they can deal. He tells Harry that a bomb will go off at 3 pm that afternoon unless the Home Secretary publicly absolves two suspected terrorists of any wrongdoing. If he can do that, he will then have more important information for him. As the MI-5 team try find the location of the bomb and Harry tries to convince the Home Secretary of the necessity of making a statement, they also have to deal with another problem: the CIA, which also has a interest in Khordad.
10 November 2008MI-5 try to stop a ruthless City financier who is out to force the collapse of a major bank. Manipulating the market is Alexis Maynell's specialty. Ros Myers goes undercover to seek evidence that Meynell is spreading the rumors that the bank in question, Highland Life, is about to go under. The Minister is prepared to freeze Meynell's assets, but only if MI-5 can find concrete evidence that he is involved in insider trading and market manipulation. Ros' life is in danger however when her cover is blown. Connie James finds herself frozen out and under suspicion as Harry continues to investigate the leak around the Sugar Horse network. Harry realizes he may have made a very serious error. Jo Portman's flashbacks are beginning to affect her work.
17 November 2008With the military situation in the Middle East rapidly deteriorating and a UN Special Envoy about to hold crisis talks in London, MI-5 come across a teenager selling a highly sophisticated - and classified - electronic disruptor. It turns out the young man saw it being used in the assassination of a photo-journalist and managed to steal it when the assassin was struck by a car. They identify the assassin as one Michael Sands, a former MI-6 agent who had disappeared on an operation two tears ago and who, they assume, has now gone native. As Lucas North babysits the young thief and his mother, the rogue MI-6 agents try to recover something other than the weapon itself. Harry meanwhile receives a coded message from a sleeper agent in Russia indicating that Sugar Horse has been compromised and that she is coming to England. What he doesn't realize is that someone is also trying to frame him.
24 November 2008Sugar Horse is revealed to be a network of sleeper agents in Russia. They are there for use only in the direst of circumstances. Just as the West's relations are on the brink - there is much sabre-rattling when the US announces its plans to install its missile shield in former Eastern European countries - two Sugar Horse agents are apparently murdered. All of the evidence points to Harry Pearce who is arrested and is forced to undergo severe questioning. Lucas North travels to Moscow to see what he can learn. A member of the MI-5 team is revealed as a Russian mole and is now desperate to be extracted after killing another member of the team.
8 December 2008With the Russian mole inside MI-5 now in custody, the team tries to decipher the information Lucas North obtained in Moscow. It is apparent that the Russian intelligence service had their own equivalent to the British Sugar Horse network and have sleeper agents across Britain and throughout the various security agencies. Information from the mole indicates that a thermonuclear device will be exploded in central London and offers to reveal the identity of all sleeper agents in the UK if they agree to provide protection and a relocation package. The Russians have issued instructions to kill Harry Pearce and all of the members of Section D so getting to the mole's information will be difficult. Harry decides to meet his Russian counterpart to ensure he knows that they will all die if they don't work together to stop the bombing.
