With a devouring thirst for blood, Countess Elizabeth Bathory (Anna Friel, "Limitless") was one of the most creative serial killers in history. Tearing flesh from bodies and bathing in warm blood, she delighted in an unholy crusade for immortality while her country was being torn apart by a brutal and devastating civil war. Set in the 17th Century, "Bathory: Countess of Blood" is based on the true story of her rise and fall.
