Detective Inspector Jacques Clouseau is borrowed from the Surete on special assignment for Scotland Yard in hopes that a fresh outlook will help the government recover the loot from the Great Train Robbery, which is being used to underwrite a new crime wave. What they don't count on, however, is having more than one Clouseau on the job.

George Smiley, the aging master spy of the Cold War and once heir apparent to Control, is brought back out of retirement to flush out a top level mole within the Circus. Smiley must travel back through his life and murky workings of the Circus to unravel the net spun by his nemesis Karla 'The Sandman' of the KGB and reveal the identity of the mole before he disappears.

Called out of retirement to settle the affairs of a friend, Smiley finds his old organization, the Circus, so overwhelmed by political considerations that it doesn't want to know what happened. He begins to follow up the clues of his friends past days, discovering that the clues lead to a high person in the Russian Secret service, and a secret important enough to kill for.

Thirty-Minute Theatre is an anthology drama series of short plays shown on BBC Television between 1965 and 1973, which was used in part at least as a training ground for new writers, on account of its short running length, and which therefore attracted many writers who later became well known. Thirty-Minute Theatre followed on from a similarly named ITV series, beginning on BBC2 in 1965 with an adaptation of the black comedy Parsons Pleasure. In 1967 BBC2 launched the UK's first colour service, with the consequence that Thirty-Minute Theatre became the first drama series in the country to be shown in colour.
