While flying mail across the Andean mountains, Henri Guillaumet's plane has to crash-land, he must trek back to civilizatin on foot.

In 1920's South America a small group of French pilots struggle to prove they can offer a reliable airmail service over the Andes. When one of the young pilots crashes on such a flight he has to try and get back to civilization on foot. Back home, his wife and colleagues start to fear the worst.—Jeremy Perkins {J-26}
