They're about to learn they're wrong....dead wrong.

An abandoned prison. A dark past. An evil that will not die. 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 brutality; a chilling reminder of man's morbid and murderous nature. Seeking to explore the violent history of the uprising, a naive crew of filmmakers invades the decaying penitentiary, only to discover that a band of fugitives has taken refuge inside the empty prison. Fearful for their lives, the filmmakers soon discover that the convicts may be the least of their problems.
