Night Plane from Chungking

Night Plane from Chungking (also known as China Pass and Sky Over China) is a 1943 American war film released by Paramount Pictures, directed by Ralph Murphy, and produced by Michael Kraike and Walter MacEwen from a screenplay by Lester Cole, Earl Fenton and Theodore Reeves, adapted by Sidney Biddell from the 1931 story by Harry Hervey.

Among the stranded passengers met by U.S. pilot Nick Stanton (Robert Preston), are a beautiful Red Cross nurse, Ann Richards (Ellen Drew), and her traveling companion, Madame Wu (Soo Yong), who is on a secret diplomatic mission.

Another of the passengers, Doctor Van der Linden (Stephen Geray), goes missing, but returns with food he claims comes from a nearby monastery.

"For this is another in the growing list of Hollywood melodramatic exercises in which the war is dragged in simply to give an old story formula a semblance of freshness.
