The narrative follows Betty and her circle of college friends as they enter junior year at Harding, chronicling their club activities, personal quarrels and reconciliations, efforts at campus reform and charitable projects, and a summer trip to Nassau that prompts social growth and renewed friendships. Episodes trace Georgia Ames's social ambitions and setbacks, the Merry Hearts club undertaking work, misunderstandings involving an authority figure, dress-reform debates, and reunions that bring characters back to practical responsibilities. The tone balances light comedy and moral instruction while showing the girls learning responsibility, cooperation, and self-possession through social events, creative enterprises, and travel.
