Another serial killer, this time preying on young women who all attend the same church. In order to catch him, Nick must try to overcome his fear and loathing of the Church and its symbols. Meanwhile, flashbacks to 15th Century France show Nick's encounter with a young peasant girl doomed to become a martyr when her claims that God spoke to her result in the Church branding her as a heretic and condemning her to burn at the stake. Nick offers her his version of immortality, but she refuses in favor of her own belief in life after death.

Nick investigates the death of a young doctor when Natalie is unable to determine the cause. Intrigued by the doctor's experiments in near death experiences, Nick secretly agrees to "go under" in an attempt to reconcile his own past. But the experiment goes awry and Natalie must find a way to bring Nick back form his altered state of consciousness.
