Demonia

In Sicily, 1486, a mob from the village tortures and crucifies five nuns in a chamber beneath their convent, suspected of witchcraft. The brutal act is framed by whispers of occult rites and a lasting sense of dread surrounding the monastery. The incident establishes a supernatural seed that will haunt later events.

During a seance in Toronto, Liza experiences a vivid vision of the crucified nuns and collapses screaming to the floor. The vision unsettles her and foreshadows a link between the past atrocity and the present investigation. The incident sets the tone for the supernatural mystery.

Months after the Toronto seance, Liza and Professor Evans lead a survey team to Ancient Greek ruins near Santa Rosalia, Sicily. The locals urge them to respect warnings about the nearby monastery ruins that overlook the dig. The decision to continue reveals a curiosity that will draw them into danger.

Locals tell the survey team to stay away from the monastery’s beautiful but ominous ruins that overlook the dig. Professor Evans cautions against involving themselves with the supernatural after the Toronto seance. Liza remains fascinated by the rumors and presses the investigation.

Ignoring warnings, Liza enters the monastery crypt and searches behind a wall she believes hides another chamber. She breaks through and uncovers the charred remains of the five nuns. When she reports her discovery, Evans angrily orders her to forget what she saw.

Soon after the discovery, supernatural murders begin. Porter is killed on his boat by a harpoon-wielding spectral nun, signaling the return of the monastery’s dark history. The team realizes the danger is real and not just a legend.

Two team members, Sean and Kevin, are lured into the ruins by enticing female voices and fall through a weak floor into a pit of metal spikes. The brutal trap confirms that the supernatural force is actively targeting the dig team. The deaths heighten tension and fear among the survivors.

Inspector Carter from Interpol arrives to investigate the string of deaths. He begins coordinating the investigation and interviewing the team, while the region’s ominous history continues to weigh on everyone. The arrival brings an official perspective to the escalating horror.

Liza meets a strange-looking woman who tells the full tale of the ruins: centuries ago the nuns practiced witchcraft, held orgies, drank blood, and murdered youths who were invited there. The revelation deepens the mystery and confirms the supernatural origin of the events. A subsequent attack claims the old woman, clawed to death by her cats.

That evening, the butcher Turi is killed in his meat shop freezer. A torn piece of clothing found in his hand points to his killer and broadens the circle of suspicion around Professor Evans. The team dynamics grow tense as fear spreads.

With Turi’s murder, Evans considers abandoning the dig and leaving the ruins behind. Liza, however, grows increasingly unhinged and refuses to leave, aligned with the spirits she perceives. The conflict deepens the sense that someone or something will not let them escape.

The enraged townspeople attack the haunted ruins as the danger escalates. Liza and Robby, the young son of two team members, go missing, kidnapped by a white-robed, faceless nun. Robby manages to escape but witnesses his father being torn apart by a hidden trap.

The pursued chase ends with Liza, dressed in a white robe, possessed by the nuns’ spirits, stabbing Evans in the stomach and disappearing. The townspeople flood into the hidden chamber, and Liza reappears foaming at the mouth on a cross, seemingly becoming one with the undead ritual.

The mob sets Liza and the skeletal remains of the nuns on fire. Evans staggers into the cavern and finds Liza at the foot of the burning crosses, no longer possessed but dead. The ritual ends with the destruction of the chamber and a somber aftermath for the investigators.
