All I know is that its about a group of teens who go to an abandoned town while they are out camping and head into a place called the house of wax where they find out that all the wax statues are actually people covered in Wax.......that is pretty much what I know from just watching the trailer. Havnt tried to look it up yet.
Here is a link to the Trailer Page:
