Until he meets Doctor Kay, a mysterious doctor who introduces himself as a "Messenger." He claims that he can sense when certain people are about to die, and that he is sent to help them put their life in order before it's too late. Nathan doesn't believe a word of this, but soon afterwards he witnesses some disconcerting scenes which seem to confirm the doctor's claims.
