Plot Outline:: Set in New Jersey, a power outage in town releases four psychotic inmates of a mental institution, held in their own floor by electricity-controlled doors. Interesting twist. Before that, they had formed a grudge against their new doctor, Dan Potter, who they have convinced themselves as the killer of their old, beloved doctor, who has actually just transferred to somewhere else.
