Skeptical female psychologist Kristen Bouchard joins David Acosta, who is training to be a Catholic priest, and a blue collar contractor as they investigate the church's backlog of unexplained mysteries, including supposed miracles, demonic possessions and other extraordinary occurrences. Their job is to assess if there's a logical explanation or if something truly supernatural is at work, examining the origins of evil along the dividing line between science and religion.
