2013: Durst's interview with Jarecki begins with his childhood, when he witnessed his mother's suicide. His father, Seymour - distant and cold, obsessed with building the Durst Organization into a real-estate behemoth and leaving his mark on the Manhattan skyline - pressures young Robert to join the family business. Durst describes his disinterest in following in his father's footsteps, and recalls meeting Kathie McCormack, a beautiful girl from a modest background. The couple fall in love and move to Vermont, where they lead a simple life and run a health-food store called All Good Things. But not long after, Seymour prevails and Robert returns to New York to take his place at the powerful Durst Organization.

1982: Robert and Kathie have been married for nearly ten years, during which they have moved from their idyllic life in Vermont back to New York City. They divide their time between a penthouse apartment on Riverside Drive, and an upstate house on picturesque Lake Truesdale, 50 miles north of Manhattan. After a weekend at the lake house, Durst walks into the 20th Precinct and tells desk sergeant Michael Struk that he hasn't seen his wife in five days. He says that when he last saw her, he was putting her on a train in Katonah to return to NYC for medical school classes. The details of their last weekend together are a subject of much controversy by those who know the couple. Believing Robert knows more about Kathie's fate than he is letting on, her family and friends embark on a hunt for the truth.
