Detective John Prudhomme, a Cajun people transferred to Chicago, is assigned to investigate the savage murder of a man who has bled to death from a severed arm. A message, "He Is Coming", written in blood on the victim's window, is a dark, foreboding clue. After two more victims with missing body parts are discovered, Prudhomme realises he is on the trail of a serial killer who is using the missing body parts to reconstruct the "Body of Christ" in time for Easter.
