Phantasmagoria

Successful mystery novelist Adrienne Delaney (Victoria Morsell) and her photographer husband Don Gordon (David Homb) along with her pet cat Spaz have just purchased a remote mansion off the coast of a small New England island previously owned by a famous 19th-century magician, Zoltan "Carno" Carnovasch (Robert Miano), whose five wives all died mysteriously. Adrienne hopes to find an inspiration for her next novel in her new home, but starts having nightmares immediately upon moving in. She is comforted by the loving and supportive Don. Adrienne explores the estate, making mysterious discoveries like strange music, warnings written on her computer, and ominous messages from a fortune-teller automaton. Unbeknownst to the happy couple, Carno had practiced black magic when he lived in the mansion and had summoned an evil demon that possessed him and caused him to murder his wives.

During her exploration of the grounds, Adrienne finds a secret chapel hidden behind a bricked off fireplace. After opening a locked box atop an altar, Adrienne unknowingly releases the demon that possessed Carno, which then possesses Don. Don starts acting menacingly towards Adrienne and drinking heavily, culminating in him assaulting her later on. Adrienne meets Harriet Hockaday (V. Joy Lee), a superstitious vagrant, and her strong but dim-witted son, Cyrus (Steven W. Bailey), who are secretly living in a barn on the estate. After Adrienne agrees to let them stay, they volunteer to help around the mansion, though Don disapproves. When a technician named Mike (Carl Neimic) visits the mansion to install the phone-line, Don screams at him in a jealous rage, warning him to stay away from his wife. Spaz also goes missing with Adrienne later discovering Spaz's collar where Don had been sitting by the fireplace earlier.

While the local townspeople believe all Carno's wives died of natural causes or accidentally, Adrienne learns through a series of visions that he murdered them in grotesque ways. Hortencia (Christine Armond), who avoided Zoltan's abuse by secluding herself in her greenhouse, (especially after the death of their daughter, Sofia, who drowned in the castle pond, suspecting Carno himself to have been responsible), was stabbed with gardening tools and then suffocated with mulch. Victoria (Holley Chant), an alcoholic, was killed when Zoltan impales her eye with a wine bottle during an argument. An overly talkative third wife, Leonora (Dana Moody), has her mouth gagged and then her neck contorted in a torture device. Finally, the food-loving Regina (Wanda Smith) was force-fed animal entrails through a funnel until she choked to death.

Harriet performs a séance for Adrienne, in which she vomits a green ectoplasm that takes the form of Carno. A repentant Carno tells her that he was possessed by the demon when he tried to learn black magic to use in his performances. He reveals that the previously trapped demon must be stopped and only she can contain it once again. Adrienne is later horrified to discover Spaz's dead body in the garden.

Adrienne visits the nearly 110-year-old Malcolm Wyrmshadow (Douglas Seale), who is being cared for by Ethel (Lilyan Chauvin); Malcolm had been Carno's apprentice as a young boy and reveals that Carno met his demise after his last wife, Marie (Traci Clauson), who was tired of being abused by him, discovered he was a murderer. Marie conspired with her secret lover, Gaston (Jeff Rector), Carno's prop master, to kill Carno by sabotaging the equipment for his most dangerous escapology trick; "The Throne Of Terror", in which Carno donned a burning hood and escaped from bonds on a throne underneath a swinging axe. The sabotage left Carno horribly burned/disfigured and falling into a coma, assumed dead, but he astonishingly survived and then attacked Marie and Gaston, mutilating them both. After killing Marie by beheading her with the throne, Carno was then impaled by Gaston, before succumbing to his own wounds.

Malcolm that reveals that it was he who had originally sealed the demon in the estate's chapel and also tells Adrienne about a ritual that can eradicate the demon. Later that night, Mike leaves the mansion, finally having completed installing the phone-line, but is then murdered by Don with an axe. Harriet, fearing for her safety, decides to leave with Cyrus as Don becomes more abusive and erratic.

The next day Adrienne discovers she cannot leave the mansion and later finds a collection of photos of her in Don's darkroom which have her head cut off. She is confronted by Don, who is now completely insane and dressed like Carno. Adrienne scars Don's face with acid from his darkroom when he tries to kill her and flees, discovering the corpses of Mike, Harriet and Cyrus hidden throughout the mansion. Don captures Adrienne and straps her into the throne, but she distracts him long enough to free herself and trigger the swinging axe, which impales and kills Don. His death unleashes the demon, which pursues Adrienne throughout the mansion. She escapes long enough to perform the ritual to trap the demon once again. The game then ends with Adrienne walking out of the mansion with a vacant stare, almost catatonic.
