When a fresh drop of blood appears on the scry map, highlighting a small mining town in Western Pennsylvania, Constantine learns that several miners have been mysteriously killed. He deduces that these were caused by Coblynau, normally benign spirits of deceased miners who are being summoned and forced to kill. In town John bumps into Zed Martin, a woman with a mysterious past, and who recognizes him as the man who has been appearing in her visions. Constantine realizes that she has psychic powers, and uses her in his investigation of the town. They discover that the source of the curse is a Romani woman who summoned the spirits to punish the mine bosses and kill her husband. After the woman is killed by the spirits she summoned, Zed agrees to join in John's fight against the coming evil.

  • Constantine's driver's license on line 5 gives his number as "CONST6610-1-ABFC121-1". This is not a correct UK driving license number, which should consist of the first 5 letters of his surname and then his date of birth jumbled, followed by the first 2 initials of his first name (if only 1 initial the second will be a 9), then computer check digits (in case there is someone else with the same name and date of birth), then a space and the issue number. There are no "-" in the driving license number and the only space is between the driver number and the issue number. In reality, Constantine's license number would likely be "CONST805102J99AB 35".
  • To distract the security at the mine, Constantine uses a nearby backhoe loader, dumping the rocks on its bucket. However, the lever he uses to do so is handbreak, not an attachment control lever.
