Soviet agents Sergei Rublev and Vladimir Zelenski so successfully infiltrated the culture they were sent to spy on in 1965 that they have become more English than the English. Now living as financier Jeremy Coward and brewery worker Albert Robinson, the "sleeping" spies are horrified to learn that, after 25 years, the KGB is looking for them. The hunt also awakens the bumbling bureaucrats of MI5 and their ultra-paranoid CIA counterparts, who work themselves into a lather trying to figure out what the KGB is up to.

The poignancy of the sleepers' predicament plays out amid a hilarious cross-cultural send-up of the secret agent game. Nigel Havers (Manchild, A Perfect Hero) and Warren Clarke (Dalziel and Pascoe, The Onedin Line) star in this touching human comedy, remembered as one of the best British experts of the 1990s.
