During the early days of glasnost, laborers in the Kremlin discover a massive hidden chamber made up to look like a British neighborhood, meticulously researched and outfitted as part of some unknown operation. Major Nina Grishina (Joanna Kanska, CAPITAL CITY) discovers files that suggest it was an unauthorized operation conducted by Andrei Zorin (Michael Gough, HORRORS OF THE BLACK MUSEUM) that has installed two KGB officers as sleeper agents in the UK in 1966. Traveling to the UK to discover the identities of these agents and whether they are still in the country, Nina's arrival sets off the suspicions of local operative Viktor Chekhov (David Calder, PERFUME: THE STORY OF A MURDERER) working out of the "Trade Delegation of the USSR in the United Kingdom" who believes the story of the rogue agents to be a cover for other interests, the CIA, and MI-5 caught off-guard through their assumed "buddy buddy" post-Cold War relationships. Having lived in the UK for twenty-five years and established personal and business connections, factory worker/trade unionist Albert Robinson (Warren Clarke, A CLOCKWORK ORANGE) and bank executive Jeremy Coward (Nigel Havers, CHARIOTS OF FIRE) have no intentions of going back, even if that means having to leave behind the lives they have now. With the three agencies working at odds with one another, the KGB assume Albert and Jeremy to be highly-trained professionals inadvertently signaled to undertake whatever operation they were trained for, the CIA assume that Jeremy is being targeted by the Russians for his financial acumen in wake of the USSR's financial collapse, and MI-5 has come to believe that the Russians are trying to infiltrate the British media when soccer fan Chekhov discovers that a piece of surveillance film shot in Britain that features the two agents also features definitive proof of a much-disputed point. Funny and charming, SLEEPERS is a more dramatic yet amusing take on espionage than Britain's more overtly comical contemporary chronicle of MI-5 blunders THE PIGLET FILES (1990-1992).
