Ten years after the transformation of Plumfield into a busy boarding school and college, the original children have grown up and scattered into the world. Franz is working with a kinsman in Hamburg, Emil is a joyful sailor, and Dan wanders from South America to Australia in search of adventure. Meanwhile, Nat studies music at the conservatory, Tom struggles through medical school for the love of Nan, and Demi chooses a career in journalism over the ministry, much to his mother's disappointment. The girls are equally determined: Daisy is a model housekeeper, Josie harbours theatrical ambitions, Bess is a talented artist, and the rebellious Nan doggedly pursues a career in medicine.
As the young people return to Plumfield for holidays and homecomings, they bring fresh stories of romance, ambition, and youthful folly. The narrative explores the trials of growing up, the friction between traditional expectations and modern ambitions, and the delicate process of finding one's true vocation. Through humorous encounters, such as Tom's persistent wooing of the medically minded Nan and Josie's dramatic performances, the community remains a sanctuary of warmth and guidance.
Professors Bhaer and March, alongside Meg, Jo, and Amy, continue to offer steady wisdom to their charges. The narrative follows their triumphs and near-misses, highlighting the importance of moral grounding, self-reliance, and affectionate support. The older generation observes these budding romances and career paths with a mixture of amusement and anxiety, realizing that their charges must ultimately pilot their own lives through the world.
The book culminates in a series of heartfelt reunions, farewells, and new beginnings. Nat prepares for a journey to Germany to finish his musical education, Emil returns safely from a perilous voyage as a second mate, and Dan continues his restless wandering before contemplating a fresh start in the West. Through all these changes, the enduring spirit of Plumfield remains a steadfast refuge, ensuring that the bonds forged in youth survive the trials of maturity.
