Iran, 1979. The US Embassy in Tehran is overrun by militant revolutionaries who hold their victims hostage at gunpoint. But unknown to anyone, 6 diplomats make a daring escape and find their way to a Canadian Embassy residence, where they hide away in fear of their lives. When the CIA learns of their escape, they call in Tony Mendez, an 'ace' CIA agent to get the diplomats out of Iran. So far, he's covertly 'exfiltrated' over a hundred CIA 'assets', but this time it's not spies he must rescue, but ordinary Americans. We follow the true story of how Mendez devises an extraordinary ruse - so unbelievable that it might just work. He plans to transform the diplomats into members of a Hollywood film studio and walk them out of Tehran's airport under the noses of his enemy. What happens next would remain classified for almost twenty years - a mission that, against all odds, fool the world and lead to six innocent Americans walking out of Iran to freedom.
