When her secret lover dies in flagrante, a diplomat’s wife (Lana Turner) is exhorted by her callous mother-in law to disappear for the reputations of her husband (John Forsythe) and young son. After a generation of drifting and degradation, she returned to town--and wound up killing a blackmailer poised to expose her. Arraigned as “Madame X,” can she tell the young lawyer (Keir Dullea) assigned to her defense that she’s his mother? Premier take on the oft-filmed melodrama co-stars Ricardo Montalban, Burgess Meredith, and, in her screen farewell, Constance Bennett. 101 min. Soundtrack: English Dolby Digital mono.
