Cambridge Spies

Created by Peter Moffat

On BBC Two

A tense, intellectually rigorous miniseries about idealistic young men caught between conviction and betrayal, where personal bonds and political ideology collide.

In 1934, four brilliant Cambridge students are recruited to spy for Russia. Fueled by youthful idealism, a passion for social justice and a talent for lying, they take huge personal risks to pass Britain's biggest secrets to Moscow.
