This episode covers the escalating crisis around double agent Kim Philby in Washington, DC, and the frantic exfiltration of his fellow Cambridge spy, Donald McLean. As US codebreakers make breakthroughs on wartime Soviet telegrams under the ultra-secret Venona project, the investigation closes in on McLean, who is cracking up under intense pressure and heavy drinking in Cairo and London. To save McLean before he is interrogated, Philby relies on his chaotic house guest and fellow Soviet spy Guy Burgess to act as a courier. Burgess speeds across Virginia, gets fired from the British Embassy, and escorts McLean on a weekend pleasure boat from Southampton across the English Channel to freedom. However, Burgess's unexpected decision to flee alongside McLean blows the operation wide open, raising immediate alarms in London and Washington and putting Philby directly in the crosshairs of counterintelligence.
