In a school for young girls the mistress finds it necessary to administer punishment to one of her pupils. Leaving strict instructions for the class to get on with their work, she leaves the room for awhile. During her absence the youngster, who has sorely resented her chastisement, harangues the class, and stirs them up to a rebellious mood. When the teacher returns, she is surprisingly knocked down with a form held up by numerous girls, who seize her as she sprawls on the floor. The leader obtains the birch and gives her teacher a goodly taste. Having had enough fun in this direction, they fetch a large jar of black ink and pour it over their unhappy mistress.
