Death Academy

While researching a massacre that occurred at their high school ten years ago, a group of four students manage to contact the recently released killer, who claims that he was framed by the school's current principal. Believing the man's story, the quartet bring him along when they break into the school one night to look for evidence of the principal's guilt. As the students search the building, they are picked off one by one by a hooded and masked figure who is determined to stop the truth from getting out.
