A Wilderness of Error

Famed filmmaker and writer Errol Morris is obsessed with one of America's most popularized true crimes - the murder of a pregnant wife and two young daughters on an Army base back in 1970.

After an Army hearing frees Green Beret Dr. Jeffrey MacDonald, his father-in-law demands a re-investigation. But when he sees all the evidence, he's shocked by where it leads...

Nine years after the murders of his pregnant wife and two young daughters, the guilt of Green Beret Dr. Jeffrey MacDonald is put to a civilian jury. The defense calls a surprise witness: The Girl in a Floppy Hat.

Joe McGinniss' book, "Fatal Vision" paints a not-so-flattering picture of Jeffrey MacDonald, but new evidence may prove that MacDonald is innocent.

Jeffrey MacDonald is serving more than 30 years in prison when a federal judge agrees to hear new evidence in the case.
