You never knew how much someone means until they are gone

Twenty years ago, a man was slaughtered in the cemetery. They found him sprawled on the ground with huge teeth marks in his neck, with all of his blood drained from his body. Ten years later, the same thing happened to a girl. Sprawled on the grass, all of her blood drained. Elizabeth Grayson never payed much attention to these happenings, telling her five friends, "It was something of the past". When Halloween is just around the corner, Elizabeth comes up with an idea that the rest of her friends aren't very fond of. They try to convince her it's a bad idea, but the decision is made. They are going to the cemetery to spend Halloween night, watching the full moon and looking for "the murderer". But soon, they realize that what they've decided on was a big mistake waiting to happen. They encounter a hideous creature that wants something from them. Something they never expected. He wants Elizabeth, and he's not about to let her out of his grasp. He's ready. Ready to take her life.
