"London Spy" is a gripping, contemporary, emotional thriller that tells the story of a chance romance between two people from very different worlds: one from the headquarters of the secret intelligence service, the other from a world of clubbing and youthful excess. Danny (Ben Whishaw) – gregarious, hedonistic and adrift, falls for the enigmatic and brilliant Alex (Ed Holcroft). Just as the two of them realize that they’re perfect for each other, Alex disappears. Danny, utterly ill-equipped to take on the complex world of British espionage, must decide whether he’s prepared to fight for the truth.
