简介：　　This British espionage thriller centers on a team of MI-5 counter-terrorist spies collectively known as 'Spooks' because of the shadowy nature of their existence. Technically speaking, Spooks don't even exist--they have no names, identities, or known locations. Yet these secret agents are all that stand between the nation and the terrorists who try to undermine national security. Matthew Macfayden heads the cast as Tom Quinn, a man struggling to deal with his double life.
