[The Dark09]

I don't remember the year it was made. But I remember some of the story very well: It's about this Average boy that's in love with this girl and when he finally becomes friends with her, her boyfriend, and their friends. They do drugs. The boy steals drugs from the pharmacy that he works at and gives them to his "friends". And when they go to the party, the girls boyfriend overdoses and dies in the car.

The girl is traumatized, and then she and the boy goes to Mexico, they have sex but the boy takes advantage it, and she gets even more traumatized. One of the friends finds out the main boy was responsible the girls boyfriend overdose. And at the end the main boy traps himself and the girl in the bathroom and he kill himself.

Sorry its poorly write. That's because I can only remember several and bits of the movie.
