In the early 1970s during the Cold War, the head of British Intelligence, Control (Sir John Hurt), 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. George Smiley (Gary Oldman) 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 rogue Agent Ricky Tarr (Tom Hardy), 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.

At West Point Academy in 1830, the calm of an October evening is shattered by the discovery of a young cadet's body swinging from a rope just off the parade grounds. An apparent suicide is not unheard of in a harsh regimen like West Point's, but the next morning, an even greater horror comes to light. Someone has stolen into the room where the body lay and removed the heart.
