One of Them 2003 on netflix

A school full of seeming good Samaritans turns out to be a front for evil in this exercise in horror. Five teenagers are enjoying a late-night ride when their car loses control, and they find themselves stranded in the middle of nowhere. The kids are taken in by the staff of the Marquez Academy, a private school not far away, but they soon discover their benefactors have a sinister side, and as they try to find out the truth about the Academy and its staff, they learn that many of the local townspeople hate and fear the academy and its students — and with good reason.
