The story begins on a miserable February day in a dreary London women's club, where Mrs. Wilkins, trapped in a drab marriage and narrow life, spots a cryptic advertisement in The Times: To Those who Appreciate Wistaria and Sunshine. A small mediaeval Italian castle on the shores of the Mediterranean to be let furnished for April. Prompted by an uncharacteristic impulse, she approaches Mrs.
Arbuthnot, a similarly repressed woman whom she only knows by sight from church, where Mrs. Arbuthnot efficiently marshals poor children. Both women have been secretly dreaming of escape, saving meager funds for a rainy day that has finally arrived.
Realizing they cannot afford the venture alone—or justify it to their conventional husbands—they decide to advertise for two more companions to share the rent. They are soon joined by the stunning, cynical Lady Caroline Dester, who is desperately fleeing the exhausting demands of her social circle, and Mrs. Fisher, a formidable and elderly Victorian relic who wishes only to sit in the sun and remember the famous literary figures of her youth. Despite their starkly contrasting personalities, generational gaps, and initial stiffness, the four women pool their resources and secure San Salvatore, an ancient castle perched on the Italian coast.
Upon arrival, the transformative effect of the Mediterranean landscape and overwhelming floral beauty works immediate magic on their spirits. The oppressive weight of their domestic obligations, loveless marriages, and rigid social duties begins to dissolve in the golden light. Mrs. Wilkins blossoms into radiant serenity, while Mrs.
Arbuthnot confronts the emotional emptiness of her self-sacrificing existence. Even the aloof Lady Caroline and the stern Mrs. Fisher slowly soften under the pervasive influence of the idyllic surroundings and unhurried peace.
The fragile harmony is playfully disrupted when the husbands—and eventually a prospective guest—decide to visit, bringing the rigid realities of the outside world into their sanctuary. Mr. Wilkins arrives unexpectedly, expecting the usual domestic arrangements, only to be effortlessly absorbed into the peaceful rhythm of the castle. As the month draws to a close, the barriers between the characters melt away, leading to profound emotional reconciliations, unexpected romances, and a renewed appreciation for life's simpler joys. The novel closes on a note of gentle hope, suggesting that beauty and love can redeem even the most stagnant lives.
