High Risk (1976)

Four medical missionaries are being held captive by the country that they were visiting; it seems that they treated some of the rebel leaders, so the government has deemed them enemies of the state. Of course the U.S. wants to help them but they feel that a rescue operation is not the best way. So, they hire some people to steal the country's national treasure, which is currently on display at their embassy in Washington, so that they could have some leverage on the President of the country who is holding the Americans. But it's not going to be easy.
