A "Wilderness of Error" is a five-part documentary series based on the book of the same name by filmmaker and author Errol Morris, who also appears in the series. When Green Beret Army surgeon Jeffrey MacDonald is sent to prison after being convicted of killing his pregnant wife and two young daughters, a storm of swirling narratives challenges the very ability to find the truth all the while overshadowing the chilling possibility that MacDonald may be an innocent man. Marc Smerling re-investigates the complicated case that has spanned decades in an attempt to find the truth.
