Former US president Jimmy Carter talks on television for the first time about the episode that, more than any other, led American voters to eject him from the presidency. Iran's seizure of the US embassy in Tehran and the holding of its staff for 444 days took more and more of Carter's time and energy. His final days in office were dominated by desperate attempts to secure the release of the embassy hostages. The other side of the story is told by top Iranians: Ayatollah Khomeini's close adviser, Grand Ayatollah Montazeri; his first foreign minister, Ebrahim Yazdi; his negotiator with the US, Sadeq Tabatabai; and the founder of Iran's Revolutionary Guard, Mohsen Rafiqdoust.
