Boo

For years, Santa Mira hospital's ghostly legends and dark past made it a hotspot for teen dares. On Halloween night, five teenagers enter the abandoned building, only to find the hauntings are real. At the same time, a trainee cop searching for his missing sister teams up with an ex-Blaxploitation star turned cop. Trapped inside with the teens, they must fight together as sinister spirits possess victims one by one, leaving everyone unsure who's alive and who's already a ghost.
