Housed inside a vault in the basement of an abandoned school lurks an evil that has been locked away for over a hundred years. When a teacher and 5 students visit the school to archive any memorabilia before it's torn down, they mistakenly free the horrific spirit, turning the school into a deadly prison. Now they must face the evil and banish it to the vault once again before it kills them and escapes to destroy the world...

In this sequel, two juvenile detention officers must escort a group of criminally-inclined urban kids to the country where they are being forced to renovate a shelter for teens as punishment for their crimes. After one of them is shot by a local, the survivors seek refuge in the home of a voodoo woman, where they mistakenly summon legendary clown-faced demon Killjoy who begins hunting them down one by one.
