Well like a said up there it's a scary movie where people get killed. The killer wears a mask, I think it was white. One girl gets killed in a hot tub and it shows her blood turning the water red. Another girl gets killed while in this room of like mirrors and she can't find her way through because there's so many mirrors. I don't think it was a very old movie, it was probably made within the last 10 years or so.
PLEASE HELP!
