Tinker Tailor Soldier John

In the early 1970s during the Cold War, the head of British Intelligence, Control, resigns after an operation in Budapest, Hungary goes badly wrong. It transpires that Control believed one of four senior figures in the service was in fact a Russian agent - a mole - and the Hungary operation was an attempt to identify which of them it was. Smiley had been forced into retirement by the departure of Control, but is asked by a senior government figure to investigate a story told to him by a rogue agent, Ricky Tarr, that there was a mole.

In the early 1970s during the Cold War, the head of British Intelligence, Control, resigns after an operation in Budapest, Hungary goes badly wrong. It transpires that Control believed one of four senior figures in the service was in fact a Russian agent - a mole - and the Hungary operation was an attempt to identify which of them it was. Smiley had been forced into retirement by the departure of Control, but is asked by a senior government figure to investigate a story told to him by a rogue agent, Ricky Tarr, that there was a mole. Smiley considers that the failure of the Hungary operation and the continuing success of Operation Witchcraft (an apparent source of significant Soviet intelligence) confirms this, and takes up the task of finding him. Through the efforts of Peter Guillam, Smiley obtains information that eventually leads him to Jim Prideaux, the agent at the heart of the Hungary fiasco…

Based on the classic novel of the same name, the international thriller is set at the height of the Cold War years of the mid-20th Century. George Smiley (Gary Oldman), a disgraced British spy, is rehired in secret by his government - which fears that the British Secret Intelligence Service, a.k.a. MI-6, has been compromised by a double agent working for the Soviets.

Tinker, Tailor, Soldier, Spyfinds George Smiley (Gary Oldman), a recently retired MI6 agent, doing his best to adjust to a life outside the secret service. However, when a disgraced agent reappears with information concerning a mole at the heart of the service, Smiley is drawn back into the murky field of espionage. Tasked with investigating which of his trusted former colleagues has chosen to betray him and their country, Smiley narrows his search to four suspects - all experienced, skilled and successful agents - but past histories, rivalries and friendships make it far from easy to pinpoint the man who is eating away at the heart of the British establishment.

The man he knew as "Control" is dead, and the young Turks who forced him out now run the Circus. But George Smiley isn't quite ready for retirement especially when a pretty, would-be defector surfaces with a shocking accusation: a Soviet mole has penetrated the highest level of British Intelligence.
