In fact, the beginning of the movie is the end of the whole story. Anna's body is only half a head on the beach, and Lucy's three cars have been abandoned for a long time and covered with weeds.
Most importantly, Lucy's eyes are bicolor, left black and right blue, while Anna's eyes are blue. So the old vampire's soul exchange spell succeeded, and the soul in Lucy's body belonged to Anna.

This film tells the story of a young girl, Lucy clervaux (Lucy clervaux), who finds a job in a nursing home. On her first day at work, she went to an ancient villa deep in the forest in the suburbs to take care of Deborah Jessel (Marie-Claude Pietragalla), a former ballet teacher who fell into a deep coma and relied on medical equipment to maintain her life.
Legend has it that this villa contains priceless treasures. At the instigation of her boyfriend William (Félix Moati), Lucy and their friend Ben (Jeremy Capone) dive into the villa to look for treasure on a Halloween night.
However, after some searching, it seems that there are others in the villa besides Mrs. Jessel, that is, the daughter whose wife should have died a long time ago. Strange terrorist incidents have happened one after another, and Lucy and them will have an unforgettable night. Whether they are alive or dead is unknown.
