How 5 Cambridge Graduates Penetrated MI6 and MI5 for the KGB

How did five young aristocrats from Cambridge University become the KGB's most productive and destructive spy ring inside British intelligence? In 1949, American codebreakers working on the secret VENONA project decrypted an old Soviet teletype cable that pointed to an ongoing, catastrophic breach inside the British diplomatic establishment. The codename was HOMER. What investigators uncovered over the next three decades would shake the foundations of Western intelligence to its core—and reveal a fatal flaw not in Britain's security ciphers, but in its class structure. Why did Kim Philby, Donald Maclean, Guy Burgess, Anthony Blunt, and John Cairncross betray the country that raised, educated, and trusted them? And why did MI5 and Whitehall protect them for decades under the assumption that "gentlemen do not spy"? 🎬 Based on declassified national archives, released SVR records, and authentic memoirs, this comprehensive documentary reconstructs the architecture of the Cambridge Five—from the drawing rooms of the Cambridge Apostles in the 1930s, through the high-stakes codebreaking of Bletchley Park and Washington in WWII, to the midnight flight from Southampton and Kim Philby's dramatic confrontation in Beirut. --- 📚 KEY HISTORICAL FIGURES: • H.A.R.
