After an undercover Czech mission goes terribly wrong and a longstanding operative is tortured and killed, bureau chief George Smiley (Alec Guinness) is summoned from retirement to investigate a theory that a mole is present in the highest reaches of MI6. This John le Carre BBC miniseries is extremely measured, stagnant even, but worth watching for Guinness' impeccable performance.
