I just remember an adolescent lured them to a room, after that the trio arrives and they go in a van to a forest, the girl burns one of the kidnappers (a girl) and tries to go out of the van but they crash agaist the forest trees.
After that one of the kidnapped girls, the brunette one tries to escape but is stabbed, the other girl a blonde one is raped but manages to escape barely, I don’t remember anymore.
Sounds like Last House on the Left (2009)
