Oscar-winning director Errol Morris' riveting documentary explores the life of Fred A. Leuchter Jr., the execution specialist who worked with prisons to make capital punishment more humane. Hired by a revisionist historian to disprove the holocaust, Leuchter traveled to Auschwitz -- while on his honeymoon -- to research the matter and concluded that the gas chambers didn't exist.
The ensuing international flap destroyed his marriage and career.
