Alan Croft, a young aviator and a girl from a strict English background are stranded on a cannibal island when their plane crashes on the way to Australia. The natives worship them, believing them to be gods, until a native girl discovers that the pilot is mortal. Giving up hope of rescue, they marry in the sight of God, but when they are found by a search plane Alan is wounded and left for dead. Barbara is spurned by her friends and family as having sinned, but Alan returns to claim her legally.
