Boo
Some hospitals don’t have the 13th Floor.  Santa Mira Hospital shouldn’t have had a third.  It’s something a group of five college students discover when they enter an abandoned hospital on Halloween night only to discover that rumors about the place being haunted are very real.  Running into other people who are trapped in the hospital, they uncover the truth about a vengeful spirit who is hell bent on making sure no one, except himself, gets out alive.
