Two half brothers, one a pilot, the other a repairman at the plane factory of their father, are in a disagreement due to the envy of the younger brother, son of the first wife of their father. Then both brothers fall in love with the same woman; this causes more conflict between the two, making worse an already tense situation.

This film relates the story of Russian Princess Fedora (Louise Ferida), in Czarist times, whose royal lover is assassinated on the eve of their marriage. She pledges vengeance, only to become the victim of her vow when she falls in love again.
