Lois Ames is devoted to her job as the editor of a magazine, and her wealthy husband Fred is equally dedicated to polo and parties. Lois's long hours drive her secretary to quit, and she replaces her with Tom Sheridan, who happens to be in the office demonstrating a rowing machine. Tom likes the work and continues to advance until he is indispensable to Lois. Ruth Holman, Tom's fiancée, is jealous of Tom's relationship with Lois and with some reason, as he is falling in love with her. In the meantime, Fred is having an affair with Ann Le Maire, a woman whose interests are closer to his own. Because he feels his love for Lois is hopeless, Tom quits his job and plans his marriage to Ruth. Lois tries to patch things up with Fred, but he suggests that they divorce instead. On Tom's last night, Lois keeps him working late. Ruth is furious and storms up to the office where Lois and Tom are dining. She threatens to tell Lois's husband about their relationship, which leaves the way clear for Lois to announce her pending divorce. Ruth breaks off her engagement to Tom, and he immediately asks Lois to marry him.
观众对《大众情人》的评价两极分化，一方面认为剧情离谱、演员表现惊艳，另一方面认为编剧粗制滥造、剧情不合理。
该片以其深刻的战争描绘和人性的探讨赢得了观众的广泛赞誉。剧中的视觉效果和演员的精湛表演让人深刻体会影片的精彩之处。
它是一部值得一看的电影，通过其故事和表现手法，让观众反思剧内向观众表达的意义和人性的复杂！
这是一部非常特别的影片，没有大开大合的剧情，没有博人眼球的类型元素，没有贯穿到底的故事脉络。像是一杯温开水，看似平淡，却喝起来十分解渴。
说真的，《大众情人》看完后我真的是久久不能平静！因为这部影片确实带给人的震撼太大了！不论是剧情节奏，还是剧情尺度，都让人不敢相信这是美国剧的水平。
