Haunted High2012

Horror Vault's take

When a tremor cracks open a decades-old time capsule buried beneath their school, a group of students find themselves locked in with something far worse than detention. Ancient spirits pour out of the capsule and take hold of the adults in charge, turning the faculty into deadly threats. With no way out and no one coming to help, the students must figure out what they're really up against before it's too late. It's a supernatural siege that turns the familiar halls of high school into a hunting ground.
