Theatrical Release Information:
The Vault

In this edgy horror story, a veteran high school teacher, still smarting after the death of his wife, learns that the school where he taught for years is being torn down. With the help of five of his students, the teacher breaks into the school to retrieve souvenirs and artifacts before the school falls to the wrecking ball. However, the students discover something strange and mysterious locked up in the basement, and when they release it, they realize too late that they've unleashed a monster with the power to kill them all. The Vault stars Ted Lyde, Michael Cory Davis, and Shani Pride; it was the first directorial effort from actor James Black (not to be confused with comedy star Jack Black). ~ Mark Deming, All Movie Guide
