the death tunnel

1928, kentucky...
a horrific disease know as "the white plague claimed over 63,000 lives.
a monstrous sanatorium was built to isolate the infected and play host to bizarre experiments in desperation to find a cure.
unable to cope with the large amount of corpses, a five hundred foot underground tunnel was constructed for the removal of these bodies, hiding the enormous death number from the rest of the outside world.
and this was called "the death tunnel".

this is a terrible story for the horrific background.
the story begins at a party named "truth or scare", annual initiation party. at this party, five girls are chosen into the initiation test, who all have a link with the sanatorium. five girls, five floors, five hours and also five ghosts. that is a horrific game aiming to scare the five girls.
but during the process, there is something wrong with that building, a haunted place.
to be confessed, i don't quit like the method of thi film, aiming to scare people who wathing, without any sense. all in a words, what the fuck is it? i can't quit understand it.
