The Outdoor Girls at the Hostess House

As the Outdoor Girls enjoy an afternoon ride, a motorcycle hits an old woman, leaving her lying injured in the road. The girls take Mrs. Sanderson to the Hostess House. After Mrs. Sanderson regains consciousness, she tells the girls how she has searched for her son for years and fears that he is dead. He ran away after being unjustly accused of a crime.

The girls dread the boys' departure to fight in the war. What if they should be killed? The boys worry that the girls will find somebody else and are especially jealous of handsome Sergeant Mullins who has become friends with the girls.
