Unknown Person

A hot-shot architect returns home from his latest business trip with a surprise: an ornate old clock rescued out of a soon-to-be-demolished mansion in Amityville, New York, that brings about a seemingly unstoppable demonic force.

Now confined to a mental hospital, young Kirsty insists her supposedly dead father is actually stuck in Hell following his wife’s betrayal. Few believe the young woman’s lurid stories aside from the thrill-seeking Dr. Channard. Kirsty is undeterred and, with the help of a fellow patient, heads to Hell for a rescue.
