Sylvia West seems to captivate the middle-aged California millionaire Frederic Summers, who believes she embodies exactly what he wants: beauty, intelligence, financial independence, and a poetic soul. To be certain, he hires a private investigator to run a background check, and the assignment falls to Alan Macklin, a young man who travels from Summers’s circle to Sylvia’s hometown in Pittsburgh.
Macklin uncovers a troubling past. A librarian named Irma Olanski tells him that Sylvia spent years seeking solace in books, using literature to numb the pain from a rape by her stepfather, Jonas Karoki. The trauma drives her into a precarious path that eventually carries her to Mexico with a fanatic priest, a figure who is later killed. After those ordeals, Sylvia returns to the United States, aided by a road trip funded through sexual services paid to Oscar Stewart.
Back on American soil, Sylvia becomes friends with Jane, a sex worker who helps her after a life‑threatening accident. In order to cover medical bills, Sylvia begins offering sexual services through a transvestite madam, a turn that marks a new phase in her life and finances. She is then raped and assaulted by a client, Bruce Stamford III, who buys her silence with a payoff.
Using that money and guided by the practical advice she later receives, Sylvia pursues investments that gradually render her financially independent and even allow her to publish her poetry. The arc expands as Alan Macklin returns to cross paths with Sylvia; they fall in love, and he finally confesses that his involvement has weighed on him, having been part of an investigation connected to her husband. Though the revelation unsettles her at first, Sylvia forgives him, and the pair move toward a future together, ending on a note of cautious optimism and mutual understanding.
