While Robert Durst has captured the year's headlines with his recent arrest and controversy surrounding the documentary, The Jinx, Lifetime puts the forgotten woman Kathie (McPhee) at the center in The Lost Wife of Robert Durst. Young and wide-eyed, she falls in love with charming, yet quirky real estate scion Robert Durst (Gillies), only to find their marriage turning stranger, darker and more disturbing as time passes.

But when Kathie disappears in 1982, her family and friends are deeply disturbed that her disappearance isn't taken seriously by police. While Durst is currently in jail awaiting trial for the murder of his close friend, journalist Susan Berman, the questions linger as to what really happened to Kathie. "The Lost Wife of Robert Durst" pulls back the curtain on the world of Robert Durst and explores what may have happened between him and Kathie.
