I wouldn't be surprised Hollywood will one day borrow some idea off of this film. New York has a blackout and four nutty convicts (lead by activist Robert Carradine) goes to a High Rise apartment and haunt the tenant. Jim Mitchum plays a cop who is the only one that can stop them (sort of like Bruce Willis in DIE HARD). New World Picture edited a very important scene in the film, where they explained about the convict. Ray Milland is good also
