Alaric de Marnac, a medieval warlock, and his murderous witch Mabille de Lancré are condemned for Satanism and are executed by decapitation in a field. But before their deaths, Alaric curses the descendants of the men who sentence him, warning that their bloodline will bear the consequences for centuries to come. Centuries drift by, and a group of curious young people travels to the old battleground to search for the grave—and the possible treasure—of these two notorious figures. The expedition is led by Hugo de Marnac, the modern‑day descendant of Alaric, who drives the mission forward with a mix of skepticism and resolve.
As they explore, the group uncovers a buried chest on the grounds and carry it back to a garage to study it later. The chest proves to be more perilous than anyone anticipated: it contains the severed, yet living, head of Alaric. Once opened, the head exerts a hypnotic pull over several members of the party, bending their wills and turning some against their friends in a chilling display of domination. The tension within the group ratchets up as fear and mistrust spread, and the head’s influence seems to blur the lines between superstition and reality.
Alaric uses his control to command his thralls to exhume his headless corpse and then reunite head and body, restoring his full form and power. With a cold precision, he turns the luckless blood of a female victim into a ritual that reanimates Mabille’s skeletal form in her tomb, reviving the female necromancer as a living nightmare. The house—already tense with fear—becomes a battlefield when the dead begin to rise, one by one, to siege the living in a scenario that alternates between claustrophobic dread and outright possession.
Desperation grows as protection and bravado fail, and the survivors face a nightmarish onslaught that decimates much of the group. In the end, the last remaining member discovers a way to banish the two horrors back to Hell by exploiting a sacred medallion, turning the tide and offering a fragile, hard‑won salvation. The story is built on a blend of Gothic atmosphere and siege‑driven horror, weaving an old-world curse with a modern-day crisis as the descendants confront the consequences of past sins.
The cast—along with a number of supporting figures—adds texture to the story, including Chantal, Dale, André Govar, and Madame Irina Komarova, each contributing to the tension, danger, and eerie history that threads through the plot. The result is a cult‑classic‑tinged horror experience that lingers with its depictions of possession, resurrection, and the quest to end an age‑old nightmare once and for all.
