Night Plane from Chungking

Without lights and in a driving rain, a bus is lumbering along the muddy Assam Road en route from Chunking to the Indian border. The trip is halted when Japanese planes bomb the road and hit a munitions truck and kill many Chinese soldiers. The Chinese commander puts the wounded soldiers on the bus and directs it to a nearby secret airport where the officer in charge is Captain Nick Stanton (Robert Preston), an American attached to the Chinese Air Force.
