It starts out with some girls playing a baseball game. Later that night they go to some bar where some guys attacks a couple of them in the alley. I think they beat him up, but this guy and his friends chase after them.
Something else goes on, and basically these guys go on a killing spree chasing these girls down. At some point, the girls are on a school bus and they get stranded. The guys find them and start chasing them through the woods. Of course, most of them die.
I've been trying to figure out what this movie is for ages. It's something I saw years ago. Early 90's perhaps.
