When Dan falls to his death at a cliff, Phil blames himself and drowns himself in guilt. Dans spirit still roams the earth, and ends up haunting Phil (accidently). When Phil lands himself in hospital the day of Dans funeral, Dan will do anything he can to help Phil, but the harder he tries the harder it gets. During his attempts to reach Phil, Dan upsets the balance between the living and the dead and is left with a choice; save the world. Or save Phil.
