Desc: The Danger Signal: Directed by Erle C. Kenton. With Jane Novak, Dorothy Revier, Robert Edeson, Gaston Glass. Mary Browning, the widow of the disinherited son of wealthy Cyrus Browning, is the mother of twin boys. Browning, who believes that he has only one grandchild, offers to adopt him and give him the best that money can buy. Mary sadly gives up Ralph, keeping Robert, the other son. Ralph grows up a wastrel, while Robert turns out to be a sterling young fellow, who finds work with his grandfather's railroad. The boys fall in love with the same girl, Laura Whitman; and Ralph, thinking to belittle Robert in her eyes, has him fired. Robert saves the mails from robbery and later saves his grandfather's private car from being wrecked. Cyrus Browning finally meets Mary, whom he has not seen for many years, and she introduces him to his second grandson. The old man realizes the faultiness of his attitude and promises to make amends for the hardships of Mary's life. Robert wins Laura, and Mary's gentle influence makes a man of Ralph.
