Workmen renovating the crypt of a Catholic church are alarmed when they discover the skeletal remains of a young man buried within the concrete. The team set about trying to pinpoint the identity of the body, which appears to have been buried with the accoutrements of certain Catholic rituals. However, an unusual piece of evidence - a message in Braille buried with the corpse, turns out to be a passage from one of St. Paul's letters to the Corinthians and proves to be a vital clue in identifying both the victim, and the killer. As the team suspect that the body was never meant to be discovered, the hunt continues for the murderer, until former church reverend Father Stuart is brutally murdered in similar circumstances. Suspecting that he may have known the identity of the killer, Boyd decides to dig deeper, and the team uncover some long hidden family secrets while questioning the community and congregation. When Frankie discovers a possible biological connection between the former parish priest, Father Stuart, and the first victim, sparks begin to fly.
Featuring Simon Kunz as DAC Ralph Christie, Barry Morse as Father Sebastian Stuart and Annette Crosbie as Moira Bowen.
