La estrella misteriosa
Mary joins the war effort by becoming an ambulance driver. She later learns of Jack's reputation as the ace known as "The Shooting Star" and encounters him while on leave in Paris. She finds him, but he is too drunk to recognize her. She puts him to bed, but when two military police barge in while she is innocently changing from a borrowed dress back into her uniform in the same room, she is forced to resign and return to the United States.
