The Kidnapping of the President (1980)

During a diplomatic visit to Toronto, the U.S. President Adam Scott (Hal Holbrook) is abducted by a South American terrorist, Roberto Assanti (Miguel Fernandes), and his female accomplice, and is held captive in an armored truck booby-trapped with high explosives. The elaborate bomb keeps the Secret Service at bay until Assanti is killed. However, the explosives are timed to detonate at midnight, so Secret Service agent Jerry O'Connor (Shatner) has to find a way into the truck to rescue the President before it detonates. Also involved are U.S Vice-President Ethan Richards (Johnson) and his wife Beth (Gardner).
