In the season finale, we trace the evil paths leading serial killers Herbert Mullin and Big Ed Kemper to a last frenzy of brutal and atrocious acts that sealed their fate and prompted their arrests. Spirit medium Jennifer Lyn gives new perspective to Kemper’s vision of “the devil’s face” that was one more excuse for his senseless slayings, decapitations, and degradations for which even his mother became a victim. Jennifer describes the supernatural encounters with her kidnapper, and the revelations that defined her own path and purpose.
