Catherine "Cathy" Kean is a foreign anthropologist who travels to Bali to document and write a book about black magic. She learns of Leák magic from her lover Mahendra, who insists that this is the most powerful and feared form of black magic, one that can be used to end lives with a single, devastating act. After a ceremonial ritual, Cathy and Mahendra share a kiss as an unknown woman watches from a distance, hinting at forces watching their every move. The following night, after a brief thunderstorm, they encounter the cackling leader of the Leák cult, an elderly witch with long fingernails who is known as the Queen of the Leák.
The Queen appears but warns that her face changes with each apparition, a marker of the shifting, uncanny nature of her presence. Before departing, she shakes Cathy’s hand, and in a shocking moment, leaves behind a severed arm in Cathy’s grip. Cathy recoils in horror, dropping the arm as it crawls a short distance before vanishing into the night. The next day, Cathy and Mahendra bring bottles of their own blood to quench the Queen’s thirst, a grim ritual that deepens the binding between mortal and magical power. The Queen reveals herself only as a prehensile tongue at first, and she instructs Cathy to remove her skirt, carving a spell into Cathy’s upper thigh. The demand is chilling: Cathy must return the next night, and Mahendra is explicitly told not to accompany her.
Cathy seeks Mahendra’s help to decipher the mark on her thigh, but he can only make out the word “Leák,” leaving the rest of the incantation shrouded in mystery. At midnight, Cathy ventures into a graveyard, wrapped in a tapis. The Queen materializes with his wicked laughter, and Cathy laughs and dances with the figure as they transform into pigs, a grotesque display that signals the fusion of ritual power and primal fear. In the meantime, Mahendra’s uncle, Machesse, begins to mentor Mahendra, teaching him mantras that could counteract Leák magic. Cathy confides in Mahendra that she and the Queen can communicate telepathically, and she even admits that she envisions destroying a wall of fire—a vision Mahendra interprets as proof that she has killed someone somewhere.
As the days pass, Cathy grows ill, yet she claims the Queen can cure her that very night. During their dark appointment, Cathy’s head, her internal organs, and her entrails detach from her body, leaving a disembodied head that drifts freely under the Queen’s control. This wandering head soars into the home of a pregnant woman and devours the unborn baby, a gruesome act that appalls all who witness it. Miraculously, Cathy’s head returns to her body, the illness lifts, and the blood she ingested seems to nourish the Queen’s vitality and youth. The two women then transform into snakes, and Cathy awakens back in human form, vomiting mice in a disturbing cascade of images.
That same night, the pair move through fireballs, using their combined power to defeat one of the Queen’s enemies. An unknown woman—who turns out to be Mahendra’s former lover—watches the events unfold and later tries to intervene, only to be killed in the ensuing chaos. Machesse informs Mahendra of Cathy’s terrifying metamorphosis and urges him to prepare for what the cult might do next. The Queen reappears to Cathy only as a younger woman, detaching Cathy’s head once more and leaving her body to lie headless on the ground. Machesse finds Cathy’s severed headless body, and the townspeople rally to ward off the flying head, terrified by the horror in front of them. Machesse confesses to Mahendra that Cathy is no longer the woman he once loved, and the living and the dead are compelled to bury her body to prevent the head from reattaching.
Mahendra dreams of Cathy pleading for her body to be exhumed, a haunting echo of the power that binds them to the ancient magic. That night, the Queen and the reanimated head confront Machesse and Mahendra in the graveyard. The Queen, revealed as an old rival of Machesse, uses her powers to unbury Cathy’s body. The head reattaches, and the Queen slips into a more dangerous form, electrocuting Machesse and slitting his neck, killing him in a blaze of magical energy. The unknown woman, revealed as Mahendra’s former lover, attempts to assault the Queen but is killed in the struggle. Mahendra’s Uncle Oka arrives to defend them, turning the battle into a violent confrontation as the Queen transforms into a humanoid pig, a monstrous form that Oka pierces in the heart with a dagger.
From that clash emerges a masked figure, and the Queen shoots energy at Oka, who returns energy with his own power, culminating in a cataclysmic explosion. In the end, the dawn breaks over the graveyard as the Queen and Cathy are killed by the rising sun, sealing a grim end to a night of forbidden magic and the dangerous lure of Leák.
The story unfolds with a steady tension between scientific curiosity and ancient blood magic, painting a portrait of a modern academic entangled with a ritual power that refuses to stay contained. It examines devotion, betrayal, and the price of knowledge when confronted with forces that exist beyond the boundaries of ordinary reality. The cast’s performances—driven by a mix of longing, fear, and fatal resolve—bring to life a world where the line between dream and nightmare blurs, and where the search for understanding can pull a person into a darkness that is both seductive and deadly.
