Casanova Killers is a new crime series about love, lust, and murder--three things that, unfortunately, go hand in hand all too often. Each episode showcases the real-life stories of people who seduce their victims with devilish good looks, irresistible charm, and all the right moves. From the outside, they look like a fantasy come true, but behind the "Don Juan" façades are ugly, cold-blooded killers. A fictional writer narrates these cautionary tales of love gone way wrong.
