Freda and Daffy, two bright sisters newly settled in the country, are drawn at once to a mysterious walled garden beyond the fir trees. When they find a tiny green door hidden in ivy, they step into a world of roses, quiet beauty, and unexpected friendship, where a kind, disabled gentleman named Fibo welcomes them with warmth, wit, and artful pictures of fairies, animals, and Dreamikins. The girls' frank curiosity, mischief, and tenderness clash amusingly with their severe Nurse, who distrusts imagination and demands discipline. As their secret visit unfolds, the children learn about the Dower House, their father's future inheritance, and the possibility of returning by permission. A hopeful scheme through the village leads to delays, more play, and punishment, while their wild wartime games only deepen the tension between freedom and order. Fibo becomes a gentle guide, urging wisdom, responsibility, and practical charity, and the girls begin planning acts of kindness for the poor. Meanwhile, Dreamikins bursts in with reckless rebellion, declaring a "wicked day," painting Bertie green, and finally running away in a burst of bravado, only to charm strangers with her appetite, stubbornness, and surprising seriousness. Together these episodes create a lively tale of childhood wonder, moral testing, hidden places, and the fragile, loving adults who try to guide the children through them.
