Beths Storyline

Id like to do a horror/thriller about two girls(about 17 years old) who accidently get killed in a car accident when they met their boyfriends and went driving recklessly down the country road. Then both girls return as ghosts to haunt the 2 boys who survived the car crash as revenge for their carelessness and that they were responsible for their deaths. Leading them into having nightmares and eventually killing themselves too when really none of it ever happened (this is revealed at the end of the film).
