The narrative begins on the night of August twenty-second, nineteen twenty-seven, when Cornelia Thornwell, an eighty-six-year-old Boston aristocrat, receives the news of the execution of Sacco and Vanzetti. Her husband, the former governor, has just passed away, leaving her surrounded by a family defined by ruthless financial ambition, social pretense, and bitter property disputes. Rejecting the stifling traditions of her class, Cornelia runs away to Plymouth, taking the name Mrs. Cornell. She finds a room in the modest home of an Italian immigrant family, the Brinis, and secures a grueling job wrapping coils of heavy rope at the Plymouth Cordage plant.
Through her daily toil and her life in Suosso's Lane, Cornelia confronts the stark reality of the working class. She meets Bartolomeo Vanzetti, an idealistic Italian ditch-digger and philosophical anarchist whose devotion to justice and reading leaves a profound impression on her. As a massive strike erupts at the cordage plant, Cornelia witnesses firsthand the brutal tactics of private guards and state police, contrasting sharply with the benevolent rhetoric of mill owners like J. Lawrence Perry. Despite the hardships, she finds a sense of authentic human connection and purpose that her privileged life never offered.
Her family eventually discovers her whereabouts, leading to tense confrontations where they try to force her back into the fold of respectable Boston society. Cornelia resists their demands, maintaining her hard-won independence and her new perspective on humanity. Meanwhile, the dark shadow of the First World War looms, sweeping up the lives of the working class and threatening Vanzetti with persecution for his radical beliefs. The novel culminates in a rich portrait of a society on the brink of profound transformation, contrasting the decaying world of the Boston Brahmins with the vibrant, struggling lives of immigrants.
Throughout the story, Cornelia's internal transformation reflects a broader critique of American capitalism and class oppression. She learns to look past social labels, recognizing genuine virtue and intellectual hunger in places her former peers would never deign to look. The ending gently hints at the enduring strength of her new convictions as she chooses a path of quiet defiance, forever separated from the gilded cage of her past.
