When a gas processing plant explodes, the UK allies itself with Tazbekstan to buy their gas at reasonable prices. Sarah Caulfield, the CIA liaison officer, tells Lucas that the U.S. and Russian governments are opposed to the deal. However, with gas supplies dwindling, Rustam Urazov (Jonny Phillips), the Tazbek minister in charge of negotiation, is stalling.
The minister orders the assassination of Matthew Plowden, a British journalist who is critical of Tazbek human rights violations. MI-5 arrives too late at the coffee shop where Plowden likes to write to save him. The minister also orders a hit on Bibi Saparova (Julia Krynke), a Tazbek human rights activist whose sister was raped, tortured, and murdered by Urazov. Malcolm's replacement, Tariq Masood (Shazad Latif), develops sophisticated eavesdropping equipment hidden in a book of matches Lucas carries to the strip club at which the Tazbeks congregate to discuss plans. Jo tries to get Ruth to talk to Harry; she thinks this will help Harry to manage the pressures that are affecting him.
Tariq figures out Urazov is planning to strike against his own country in order to become Prime Minister. Jo recruits Saparova to kill Urazov. Although she succeeds, the Russians have recorded the actions and use the photographs to disrupt the negotiations. The Russians, however, are willing to sell the UK the gas at the same price in exchange for intelligence to be used against Tazbekstan. A romance between Lucas and Sarah Caulfield shows signs of developing. In the end, Blake, the Home Secretary, informs Harry of a top secret meeting that took place in Basel, Switzerland regarding a new world order, codenamed "Nightingale".
