Synopsis by Janiss Garza
In 1916, Marguerita Fischer starred in Miss Jackie of the Navy. During the year between that picture and this one, the United States entered World War I, so it seemed like a good idea to bring back the spunky character of Jackie, this time as a teenage Army brat. Jackie spends most of her time driving her father, Colonel Kerwood (Hal Clements), up a wall. She also has a sweetheart, Lieutenant Adair (Jack Mower). The plot thickens when Jackie suspects her lover of being a spy for the Germans. When she looks more deeply into the situation, she uncovers a group of traitors who are going to blow up a train loaded with military officials. With the help of her Lieutenant -- who, it turns out, was innocent all along -- Jackie foils their scheme and saves the day.
