From the liner notes

Several years ago, a bloody riot of epic proportion ravaged the corridors of the Isla del Roca penitentiary, resulting in the gruesome death of both inmates and guards alike.Now condemned, the prison serves as nothing more than a shattered relic of archaic brutality; a chilling reminder of man’s morbid and murderous nature. Seeking to explore the violent history of the uprising, a naïve crew of filmmakers invades the decaying penitentiary, only to discover that a band of fugitives has taken refuge inside the empty jailhouse. Fearful for their lives, the filmmakers soon discover that the convicts may be the least of their problems – and that the victims of that fatal riot may still haunt the prison walls. Jake Busey (The Frighteners), Stacy Keach (American History X), and Danny Trejo (From Dusk Till Dawn) star in this terrifying splatterfest from critically acclaimed horror maestro Kevin Van Hook.
