The final act finds Emily no longer herself but the ancient witch Naga Soth who has slipped into Emily’s body through the blood‑stained Ouija board. Baptiste, the descendant of Bishop Grogan and self‑appointed master of the cursed relic, has been using the board to force the exchange, hoping to wrest the witch’s power for his own. When the ritual completes, the centuries‑old spirit awakens in the present while Emily’s soul is trapped in the past, leaving the witch free to exact revenge on the modern world.
Back at Baptiste’s sprawling mansion, the witch‑possessed Emily begins serving the restaurant’s debut dish—rice infused with the crimson mushrooms harvested from the corpse in the woods. The meal drives the diners into a murderous frenzy, and a chaotic bloodbath erupts. Christian fights his way through the carnage, but the police arrive and mistake him for the killer, forcing him to flee with Brooke’s help. Meanwhile, Baptiste revels in his perceived triumph, proclaiming that Emily has chosen him over the chef.
The climax erupts when Baptiste, drunk on his own hubris, dons the ancient bishop’s vestments, inadvertently re‑awakening the very fury he sought to control. Naga Soth lashes out, slaying an Asha Sister and forcing Baptiste to retreat. Seizing the moment, Christian tears the Ouija board from the altar and throws it into the flames. The fire pulls the witch back into her own scarred body on the stake, and Emily’s consciousness snaps back into her modern form just as Christian is gunned down by the arriving police. In a final burst of vengeance, Emily slays Baptiste, and Brooke helps her flee as the mansion burns to ash.
The film then jumps to the aftermath. Baptiste’s corpse is placed in a body bag, but his eyes flash open—his blood, having been spilled on the board during the ritual, has bound his soul to the cursed object just as Amelie’s blood had centuries earlier. Brooke and a restored Emily travel to the Vatican, intending to trade the board for a fortune of diamonds. Before the Pope can intervene, the spirit of Naga Soth materialises and drags him into darkness, underscoring that the board’s malevolence cannot be contained by even the Church.
Thus the ending leaves two chilling revelations: the witch is once again sealed within the board, her power forever linked to the blood of those who have tried to master it, and Baptiste’s lingering presence suggests the curse will continue to seek new victims. The film closes on the unsettling notion that anyone who dares to use the board is not merely doomed—it is damned for eternity.
