The Kopp sisters and I would be friends in real life. On the eve of US involvement in WWI, the sisters attend a women's training camp. Each faces unique challenges as she grows into her new role. There is a mysterious woman in their midst.

The sisters Kopp are back for adventure and intrigue. In rapid succession, Constance, deputy sheriff, nabs a crook, saves a runaway, and delves into a mystery at the insane asylum for women. Meanwhile, one sister has developed a master plan to help the US win a war it hasn't entered, and the other is determined to entertain the troops. Stewart takes real characters and events, then she adds the ultimate extra spin: her imagination. Excellent!
