Based on a true story:
On November 4, 1979, as the Iranian revolution reaches its boiling point, militants storm the U.S. embassy in Tehran, taking 52 Americans hostage. But, in the midst of the chaos, six Americans manage to slip away and find refuge in the home of the Canadian ambassador. Knowing it is only a matter of time before the six are found out and likely killed, a CIA "exfiltration" specialist named Tony Mendez (Affleck) comes up with a risky plan to get them safely out of the country. A plan so incredible, it could only happen in the movies.
