This third screen adaptation of Somerset Maugham's novel about the destructiveness of sexual obsession stars Laurence Harvey as Philip Carey, a club-footed artist who after two unsuccessful years in Paris decides to pursue a career in medicine instead. During his medical studies he falls in love with a waitress, Mildred Rogers (Kim Novak), who takes advantage of his attraction to her. When Mildred leaves him to marry another man, Philip falls in love with a writer (Siobhan McKenna), who encourages him to complete his studies. Under her tutelage, Philip excels in medical school. But when Mildred returns, pregnant and abandoned by her husband, Philip takes her in and cares for her, breaking off with the kind-hearted writer. Staying with Philip at his flat, Mildred has an affair with his best friend. Confronting her with her indiscretions, Mildred tells Philip how repulsed she is by his club foot and walks out on him. Philip once again throws himself into his studies, passing his examinations and taking an internship at a London hospital. There he hears Mildred has become a cheap prostitute. Philip travels to the brothel where she is living in poverty with her child and takes her under his wing once again. As before, Mildred walks out on Philip, trashing his apartment and taking to the streets. When Philip comes upon her again, he finds that her child has died and she is suffering from the advanced stages of syphilis.
