his 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. 

In 1968, Dani Limor was recruited by Mossad. To this day, virtually all of Limor's assignments remain classified. But their successes made him one Mossad's top field agents. In 1977, the Israeli State officially recognised the heritage of an ancient tribe of 90,000 Jews, who were the decedents of those fleeing Jerusalem more than 2,500 years earlier. Now, they were 1,800 miles away, in an enclave of around 500 impoverished villages, in the northwest corner of Ethiopia, a country under the control of a pro-Communist military junta and funded by the Soviet Union. It became clear the Lost Tribe were not going to make it out of Ethiopia on their own. This is the story of how Mossad sent undercover agents into enemy territory to secretly repatriate thousands from the Lost Tribes of Israel. It's one of the most daring rescue missions in the history of espionage.
