Scatterbrained Ada organizes a class in first aid, even though Ada doesn't know the difference between a break and a sprain! But the "victim" is taken sick and cannot appear for the demonstration. Then a strange man has an accident in Ada's garden. Fate has handed a victim to the first aid class! And what "the girls" do to him is a caution! Then they discover that he is a doctor who has moved next door. He goes home, groaning and complaining. The girls are crestfallen until they get another victim - and this results in a riot of howls that brings down the house.
