Overview: This episode tells the amazing story of Vladimir Vetrov, a high-ranking KGB officer and secret operative for the French Intelligence Service, during the Cold War. In December 1980, he made the decision to spy for the French Intelligence Service after spending a number of years in Paris. As a secret agent Vetrov passed more than 4,000 documents to his handlers revealing the extraordinary depth of the Soviet industrial espionage mission against the West. President Ronald Reagan’s advisors manipulated the situation to their advantage, by feeding faulty technology back to the Russians in a decade-long Trojan Horse operation which fatally undermined Soviet science and technology. In February 1982, Vetrov was arrested for the murder of a bystander and the attempted murder of his mistress, KGB secretary Ludmilla Ochinkina.
