Vampires really do exist.

Craig is a vampire hunter. He risks his life regularly in order to keep humans safe.

JD is his trainer. He is a hard task master, but his training keeps his students alive and has turned them into the best hunting team in the area.

Sarah is Craig's best friend who, until now, is oblivious to his nocturnal activities. When Craig tells her the truth about himself, she wants to know more. When JD agrees to train her, little does he knew how much she will affect his life and disrupt the lives of everyone living at Sanctuary 14.
