Based on 'The Thing on the Doorstep' with elements of 'The Dunwich Horror'
Dan Upton and Edward Derby are two students of Esoteric Religions and Cults in Miskatonic University. Things change for them when Edward hooks up with Asenath Waite, a strange girl from Innsmouth. Under her influence Derby begins to drift apart from Dan and become involved in magical rituals and strange cults.
In a seemingly unrelated incidents, the police (led by Inspector LeGrasse) are investigating a string of weird murders where the bodies have been found decapitated and drained of blood. Meanwhile Asenath's father Ephraim Waite (a notorious dabbler in the black arts) is dying and she returns home to Innsmouth for her father's last days. On her return, she seems different and more controlling of Edward – this cumulates with the police contacting Dan after Derby is found out of his mind wondering the streets of Dunwich. Edward babbles to Dan strange stories about shoggoths and other dimensions and how Asenath is controlling his body to perform in occult rituals.
The Police start to investigate a cult (of Cthulhu) that has sprung up in the area and suspect them for the murders. On further investigation, the murders have been traced to Ephraim Waite old farm house – close to where Inspector LeGrasse witnesses another murder but the assailant could not be seen. The Policeman suspects that the killer might not be of this world and recruits the help of Professor Armitage, an expert in Esoteric Arts and mysticism. Dan learns that Edward has committed himself to Arkham Asylum in an effort to toward Asenath's control of him. He has since learnt that Asenath herself was taken over by her father's spirit on his death.
LeGrasse with the help of Professor Armitage and Dan Upton try to track down the invisible killer which we learn is as big as a barn (due to the tracks it left). The Professor and Dan use ancient texts to destroy the creature but not before LeGrasse is killed. Dan Upton then goes to the Asylum and shoots Edward to stop Ephraim Waite using his body in dangerous rituals that could threaten the safety of the world. Dan then hangs himself in prison leaving a note explaining his reasons for the murder.
The Australian film suffers terribly from a lack of budget – it was shot on grainy 16mm and many shots are poorly lit. Most of the it seems to have been shot without sound and though the acting is amateurish the cast do an adequate job. Despite all this, you can't but feel that the film is a labour of love and the director being a big fan of the source material. Plot wise, it's a bit of a mess. It would have been better if they had just stuck to the Thing on the Doorstep as all the parts about the murders and the invisible monster seem out of place and tacked on. It's a nice companion piece to Strange Aeons.
- Miskatonic University is shown to be in Dunwich rather than Arkham.
- Professor Armitage mentions that he was involved with the Army operation in Innsmouth.
- Dan Upton mentions he has a copy of the Necronomican among other occult titles.
- Ephraim Waite raised the shoggoth (though its never named) on a farm in Dunwich rather than Old Wizard Whateley which is the case in the story The Dunwich Horror.
