In this late Lucio Fulci shocker, a group of archaeologists uncover the ruins of a convent where nuns were executed centuries earlier, unleashing a wave of supernatural terror. Demonia is an Italian occult and supernatural horror, fusing Fulcis trademark gore and exploitation style with a story of blasphemy, ghostly vengeance, and convent-bound dread.

NO EVIL DEED GOES UNDONE.

Like many of his contemporaries, Godfather of Gore Lucio Fulci (City of the Living Dead, Dont Torture a Duckling) found his career on a downturn at the end of the 1980s as the bottom fell out of the Italian horror movie market. While much of his latter-day output went straight to video, these low-budget productions nonetheless offer up some diamonds in the rough, among them his 1990 tale of rampaging Satanic Sisters - Demonia, regarded by many as his last great film.

A Canadian archaeological team, led by Professor Evans (Brett Halsey, The Devils Honey), descends on the ruins of a medieval Sicilian monastery to undertake an excavation. But when Evans protégé, Liza (Meg Register, Ministry of Vengeance), goes searching for an explanation to the disturbing visions shes been experiencing, she awakens the spirit of three Satan-worshiping nuns put to death centuries earlier by a violent mob, unleashing an orgy of vengeful violence on the unsuspecting explorers.

Originally destined for a theatrical release, Demonia is a return to the atmosphere and gory excesses of Fulcis late 70s/early 80s output - a no-holds-barred Satanic shocker co-starring Lino Salemme (Demons) and Al Cliver (Zombie Flesh Eaters) and co-written by Piero Regnoli (Burial Ground) - presented here in a pristine restoration and a host of extras.
