In 1920s South America, a small group of French pilots led by aviation pioneer Antoine de Saint-Exupéry (Tom Hulce) struggle to prove they can offer a reliable airmail service over the Andes. When one of the young airmail pilots, Henri Guillaumet (Craig Sheffer), crashes on such a flight in the Andes, a search is started. Henri has to try and get back to civilization on foot. Back home, his wife Noelle (Elizabeth McGovern) and colleagues start to fear the worst.
