Driven by ideals, faith or simple cruelty, the Vampire Hunters is a group of people that goes in search of "Vampires" and brutally kills them by impaling their heart. Some of them really believes in vampires, others want to clean the world from what they consider human garbage and some just wants to express their brutal nature on the innocents. All of their victims are people with an eccentric personality or psychological problems who think to be or pretend to be vampires. One of their leaders is Dr. Charles Thurston, a professor at Harvard and therapist, that uses his job to spot victims for the Hunters.
