In "Spirit of Frankenstein [Part 7]," Dr. Warren pushes the boundaries of science by crafting a lifelike plastic skin and using it to cloak a radio-controlled synthetic man built on a bullet-proof steel frame.

In January 1950, William Baber of Bristol, England, begs the British Housing Commission to relocate him after moving into a house haunted by the ghost of Mrs. It, a spectral woman in black with a glowing halo who began appearing after he opened a locked storeroom—despite a lease stipulation to keep it sealed. The haunting escalates when the ghost frightens his children, terrifies their watchdog, and even returns after an exorcism, now accompanied by a phantom partner dancing up and down the stairs.
