Fictional account of the true crime story involving Robert A. Durst and the (unsolved) disappearance of his wife Kathie in 1982. David Marks (Gosling) doesn't want to follow his wealthy father Sanford (Langella) into the family's New York real estate business. He tries rebelling, including through his marriage to Katie (Dunst), but finally succumbs to parental pressure. As David gets increasingly angry, his marriage falls apart. Then Katie goes missing. Dunst is appealing but Gosling is stuck playing a repellent cipher.
