Based upon a summary in a film publication, Angela (Pickford), an Italian girl, bids good-bye to her second brother, who is the youngest, as he goes off to join the troops. Then comes news that her older brother has been killed in the war. Giovanni (Bloomer), who loves Angela, tries to comfort her, and then he too is called. Left alone, Angela is made keeper of the lighthouse. Joseph (Thomson) arrives and says that he is an American and a deserter. They are later secretly married. One night he has Angela flash him a “love” signal using the lighthouse. The next morning an Italian ship carrying wounded men is reported as having been destroyed at midnight, the hour when the signal was sent. Angela steals some chocolate from Tony (Regas) for Joseph to take with him. When she arrives home, she hears Joseph murmur in his sleep “Gott mitt uns,” and it dawns on her that her husband is a German spy. Tony traces the theft to her, and after he says that her wounded brother had been on the ship, she realizes that it was the signal that sent her brother to his death. She gives up Joseph, who still proclaims his love for her. Joseph breaks away from his jailers and plunges over a cliff to his death. Later, with her and Joseph’s baby, Angela is happy with her old sweetheart Giovanni, who has returned from the war blind.
