The big class trip is about to begin, and the girls find themselves in a travel group led by Mrs. Drill and Mrs. Harschmann. After a long hike they finally reach their destination: a small hut in the middle of the mountains, which is unfortunately already occupied...by boys! The girls and Mrs. Drill get along with the scout group and their leader right away, but Mrs. Harschmann rages. Soon after that the forces of nature also rage.
