As new evidence is revealed, Robert Durst is arrested and charged with Susan Berman's murder. But who will support Bob in his time of need?

From jail, Bob makes frequent calls to people who've helped him in the past, including a longtime friend who is keeping his own secret.

At trial, prosecutors revisit the 1982 disappearance of Bob's first wife Kathie and make the case that Susan helped Bob cover up the crime.

Bob takes the stand to tell his version of events, but on cross-examination finds prosecutor Lewin better-prepared than he anticipated.

After Bob's death, Kathie's family files a lawsuit against his estate – forcing his friends and family to go on the record.
