The movie Argo is based on the true story. In the history the story is known as the Canadian Caper. The movie is about how the production of a fake sci-fi movie was used to rescue 6 Americans from the Canadian ambassador 's house in Teheran in 1980 after they were able to flee from the American embassy when Iranian militants stormed it in 1979.
It all started in 1950, when the Iranian people elected Mohammad Mosaddegh as prime minister. He nationalized Iranian oil industry, which was under British control since 1913. This way the Iranian population was in charge again over the Iranian oil. But in 1953 Masaddegh was removed from power through cooperation between the American CIA and the British MI6. Mahammed Reza Pahlavi was installed as Shah. He kept his power through the police and by threatening people. It was a time of threat, fear and torture began and then he started to westernize Iran and enraged the mostly Shihad population of Iran. All this ended in 1979 when the people overthrow the Shah and Khomeini returned as the supreme leader of the Iranian revolution from his exile. He spent the last 15 years in exile due to his opposition against the Shah. After Khomeini had the power in Iran it resulted in firing squads and chaos. Meanwhile the shah and his family were able to leave Iran. In 1979 the shah was given asylum in the US because he was dying of cancer. The Iranian people gathered on the streets around the US-embassy in Teheran and were demanding the shah’s return and conviction in court, which would have most likely result in hanging him.
This is where the main plot of the movie starts, which shows the crowd in front of the embassy’s gates.
During this gathering around the US-embassy in Teheran, Iranian militants were able to break through the security points and stormed the embassy and took control over it. They were taking 56 Americans as hostages but 6 American embassy staff members were able to get away and found a hiding spot
