The Iran hostage crisis was also a major issue during MacDonald's term. Six American diplomats had escaped the seizure of the American embassy by radical Iranian students and had sought refuge in the Canadian embassy in Tehran. MacDonald authorized the issuance of false passports and money to the six as part of a plan to rescue the escapees that had the Americans pose as Canadians and leave the country with Canadian staff when the embassy was closed on January 28, 1980, although she was not able to discuss her role publicly. The successful operation became known as the Canadian Caper, and it was later dramatized in the Academy Award-winning film "Argo".
