    S1:E6

    The dangerous, emotional and arduous toll of stealth ops has never been felt more deeply than by those who adopted completely separate personas to integrate themselves into a shadowy underworld. From "The Pond", an intelligence operation so secret the CIA was kept in the dark, to a luxury Red Sea diving resort covertly operated by Mossad agents, to the British security services' daring rescue of a double agent in Moscow. These undercover smokescreens were all driven by daring agents in service of executing a greater purpose.

    S2:E10

    Some rescues read like Hollywood - except they were real. In Operation Halyard, villagers and resistance fighters built an airstrip by hand to spirit stranded airmen out of Nazi territory, while Operation Mount Hope saw American forces steal a Soviet helicopter from the African desert under cover of darkness. Decades earlier, the SAS hijacked a train in occupied Italy to liberate 200 prisoners - an extraordinary feat that proved extraction can be as daring as any assault.

    To outmaneuver the enemy, you have to sell the illusion. An FBI agent goes so deep undercover he's the best man at a Mafia wedding, while the Stasi deploys a covert network of charmers across borders to win trust and steal secrets. And in Egypt, a German-born Jewish spy poses as a high-flying, champagne-soaked ex-Nazi to infiltrate its missile program for Israel. Different missions, one rule: if they believe you, you're already inside.

    S2:E12

    Some missions are so risky, they're denied before they even begin. From a covert Mossad operation to abduct a Nazi war criminal in Argentina-identified through the smallest detail, the shape of his ears-to a chilling CIA plot that used a jazz tour as cover for an assassination attempt in the Congo; to one resistance fighter volunteering to be captured and sent to Auschwitz to reveal the horrors within-these operations are proof that the most dangerous missions are often the most unthinkable.
