Allan Grey, an enigmatic traveler and student of the occult, arrives in a secluded village plagued by mysterious events. He checks into an inn, where he experiences eerie disturbances and spectral visions. A shadowy figure leads him to a nearby chateau, where he witnesses more unsettling scenes involving the inhabitants: the elderly owner of the chateau, his two daughters, and the family's loyal servants. Allan discovers that one daughter, Léone, suffers from a strange illness, marked by deep sleep and inexplicable wounds on her neck. The villagers whisper about a vampiric curse afflicting the family.

Haunted by what he has seen, Allan investigates further, uncovering cryptic messages and ancient texts about vampires. His search leads him to the hidden crypts around the chateau, where malevolent forces seem to dwell. As Allan pieces together the mystery, time races against him to find a way to save Léone and liberate the village from the vampire's grip. With mounting tension and an atmosphere thick with dread, Allan must confront supernatural horrors and decipher the old legends before darkness consumes them all.
