First Half: The investigation into the disappearance of 84-year-old Nancy Guthrie remains active. Author and former criminal defense attorney Mark Shaw will review the developments to date, including interactions with law enforcement. He'll examine whether all possible motives behind the abduction have been explored and offer his analysis.

Second Half: Professor Michael Zigarelli delves into what happens after we die. He argues that there is a surprisingly credible, scientific case that death is not our demise, but a doorway. This, he says, is supported by the thousands who have walked through that door and returned to tell about it.
