Everyone needs someone they can trust — even the head of one of the most elite spy agencies in the world!

That's the premise of this exclusive sneak peek from BBC America's new six-part series The Game, which premieres Wednesday at 10/9c. From Doctor Who scribe Toby Whithouse, the period drama stars Emmy winner Brian Cox as Daddy, the head of MI5 circa 1972, who sets up a secret committee to investigate the existence of a Soviet plot code-named Operation Glass.
