Based on a true story plucked from Highsmith's own life, Caroltells the riveting drama of Therese Belivet, a stage designer trapped in a department-store day job, whose routine is forever shattered by a gorgeous epiphany—the appearance of Carol Aird, a customer who comes in to buy her daughter a Christmas toy. Therese begins to gravitate toward the alluring suburban housewife, who is trapped in a marriage as stultifying as Therese's job. They fall in love and set out across the United States, ensnared by society's confines and the imminent disapproval of others, yet propelled by their infatuation.
