An American meteorologist is on a flight mission over the Artic wasteland with the Royal Air Force when the crew spot a wrecked Russian plane. A lone survivor is visible from the air. While the crew are unable to stop to rescue him, the American volunteers to parachute into the site with supplies and tend to the wounded man until help can arrive. As the days wear on and no-one comes to their rescue, the pair set out on an arduous journey, the American saddled with most of the work and their relationship reflecting the continued misunderstanding and mistrust between the U.S. and the U.S.S.R.
