So in this film there is a teacher, seems quite nice at first, but he kidnaps one of his students, and takes her to a wood, once there he tells her he is going to shoot himself in the head, but that he wont die, when he wakes up he is going to hunt and kill her.
So he shoots him self in the head and blows his brains out - she panics when see sees his wounds healing and runs off - then he starts the hunt.
