Synopsis by Janiss Garza
Eugene Lenoir weds the sister of Major Warfield (Tom Burrough). The couple dies not many months after the marriage, but there is much animosity between the two families. Gabriel Lenoir (Frank Evans) inherits his brother's estate, and he makes the nurse swear to kill the baby that was born to Eugene's wife shortly before she died. But the nurse takes the infant to be raised in a New York tenement instead. After the girl is grown, the nurse tells the Major of her existence. Warfield brings her back to Virginia under the name Capitola Black (June Caprice). When the United States declares war on Germany, Herbert Grayson (William Courtleigh, Jr.) comes to town to ferret out a gang of spies. Capitola decides to help her country, too, and she discovers that Gabriel Lenoir is one of the conspirators. The Major reveals that Lenoir stole Capitola's fortune when she was a baby, and the villain gets his just rewards for his wrongdoings. The estate is returned to Capitola, who settles down with Grayson.
