MI6 officer Kate Henderson meets in Malta with Lena, an asset providing intel on Russian SVR chief Igor Borodin, whose family she works for as a nanny. Lena plants a bugged cigar box in the Borodin villa. MI6 eavesdrop on Borodin speaking with operative Kyril Markov, who says they have an asset ready to replace a member of the British Cabinet who is dying of pancreatic cancer. Zak Hussein, Kate’s superior, is cautious of Russia feeding false intel and gives her 48 hours to conclude the operation. During dinner with Home Secretary Imogen Conrad, who Kate’s husband Stuart works for as a SpAd, Prime Minister Anthony Fletcher announces his resignation due to a terminal prognosis. Imogen and Foreign Secretary Ryan Walker become main contenders in an expedited leadership election. Kate discovers Imogen received an undeclared donation of £200k from Russian oligarch Lev Amatov. In a meeting with Zak, Kate and C (Alan Brabazon), Anthony demands concrete evidence before authorising investigations into any MP’s.

Kate’s colleague Rav discovers Ryan met Lev, the Russian Foreign Minister and Swiss investment lawyer Laurent Sauverre in Lisbon shortly after Anthony's announcement. The two start working off books to investigate both him and Imogen. C orders Kate to check that Sergei Malinski, her university friend and mole in the SVR, remains onside. He assures her of his loyalty and advises the SVR has flagged Malta. Kyril deduces Lena is a mole and informs Igor. Kate suspects Lena is compromised, but Zak and head of security Rose Trewen refuse to authorise an extraction. Kate plans to extract Lena herself against orders, risking her job. Growing disillusioned with his behaviour, Ryan’s SpAd Melissa Morris leaks the Lisbon meeting details to the press, but Ryan is able to save face in an impromptu interview with Robert Peston. Knowing her husband works for Imogen, Ryan questions Kate’s impartiality, and warns her not to interfere in the democratic process. Kyril forces Lena to arrange a meeting with Kate.

Kate, Rav and fellow MI6 officer Julie Price try to extract Lena from Valletta, but she is killed by a sniper working for Kyril. Kate and Rav discover Kyril’s team travelled at short notice, suggesting a tip off from someone in London who knew of the extraction plan. During her debrief, Zak discovers Kate has been investigating Imogen and Ryan and is forced to notify him. Ryan faces marriage and financial issues. Melissa resigns, and tells Imogen that Ryan may leak video of her having an extramarital affair if he gets desperate. Kate speaks to former SpAd Josh Long, who denies an affair with Imogen at a conference in Montenegro, and claims he left politics due to her closeness with Lev there. Kate also discovers Kyril was at the same conference. Rav discovers Zak also attended the Montenegro conference in secret, and the two begin to suspect he is working with Imogen and Kyril. However, C informs Kate that she and Rav have been suspended on Ryan’s orders due to Lena’s death.

Kate and Sergei plan for him to break into SVR Headquarters and obtain hard copy documents to uncover the identity of Igor’s MI6 mole and asset. Ryan causes further controversy after sharing a deep fake video, attributed to Lev’s companies, about small boat migrants attacking teenage girls, which causes disorder in Lincolnshire and Hartlepool. Imogen and several Cabinet ministers host a conference demanding his resignation. When an SVR agent stalks her daughter, Kate is forced to tell her children she works for MI6. Rose confirms to Kate that Zak didn’t log his Montenegro visit, only a flight to Dubrovnik in neighbouring Croatia. When Rose pressures Zak, he immediately calls Julie, who Kate had sent to monitor Igor’s closeted son Mikhail in Helsinki. Rose tells Kate that Zak and Julie may be working together. In Geneva, Rav covertly hacks Laurent's laptop and sends Kate evidence Ryan received payments from Igor via a Swiss bank account. Kate then finds Rav murdered in his house.

Despite proof Russia funded a building project Ryan was invested in, Anthony refuses to suspend him, believing it only shows greed not espionage. Frustrated, C approves Kate’s mission with Sergei. The affair video of Imogen is released, but conceals the man's identity. Ryan borrows a further million from Lev to protect his investment, with the oligarch remarking he backed the right man. Imogen loses the election to Ryan. In Helsinki, Julie reveals Zak was tricked into attending Montenegro by Kyril. Mikhail gives Kate the date Igor’s operation started in exchange for witness protection from his father. The paperwork Sergei then steals from the SVR places Igor in Prague before the operation commenced, the same time Kate and Stuart were there for their anniversary. Kate deduces Stuart is the mole, having been recruited by Igor who blackmailed him with footage of his affair with Imogen. She reluctantly allows him to defect across the Finland–Russia border as an alternative to being tried for treason. Ryan, now Prime Minister, declares he was elected to serve the public despite interference from the deep state. After Rav’s funeral, Zak and C have Kate seconded to the Cabinet Office to monitor Ryan, who they still believe is a Russian asset.
