This film deserves to be Whispering Corridors 5 more than the film that was released with that name. The school here is a private one up in the forested mountains with basements and caves providing some eerie sets. I wish it would have stuck with eerie and psychological. It gets a little bloody at the end. I didn't see that coming, and/but it works. The girls at the school are there because they have some disease, like tuberculosis. Their families don't want to care for them any more so they won't be missed if something happens to them. Drum roll.
