Woman, thinking herself a widow, marries an unfaithful man who flirts with other women, and spends his leave having an extramarital affair with a woman who turns out to be a German spy. Her first husband turns up later alive, making her an unknowing bigamist.

A man is shot by a female spy and left for dead by his wife. Her next husband is also shot, again by a German spy, and killed. An airplane is seen straifing a fleeing automobile and kills the driver; the car bursts into flames and overturns, killing the passenger.

Cigarette smoking and social alcohol consumption.

A final aerial battle scene is intense.
