After a short split prologue showing riches as the root of evil in ancient and modern times, the film settles into 1914 France, where the Orient Express is about to be wrecked when a bridge washes out. Among those on board are Al and Travis, Americans who are traveling Europe spending Travis' money, and Marie, a German girl. The boys save Marie after the wreck and Travis falls in love with her. When World War I breaks out Al wants to enlist, but Travis can't, feeling loyal to Marie, a German. By 1917 Al has enlisted, and Travis follows him shortly after marrying Marie. Accused of being a German spy by a Russian agent, she is sentenced to die but is recognized by Travis, who is part of the firing squad. The town they are in is shelled and they are all trapped underground, during which a minister makes a lengthy parallel to ancient times when the King of Akkad persecuted his subjects and defied Jehovah, who finally sends a flood to wipe out mankind, except for Noah and his family, whom he has instructed to build an ark and fill it with two of every creature on earth.
