A cat slips through an open window at night. In most of the world, nobody looks twice. In parts of Maluku, Papua, and the islands scattered between them, a family might watch that cat a little longer than it deserves — because the cat might not be a cat at all.
That fear is the subject of Suanggi: Ilmu Kutukan, a supernatural horror film directed by Dom Dharmo and set for release in Indonesian theaters on September 10, 2026. The story follows Beni, a broke former singer who returns to his home on the fictional Karangkas Island with a secret plan to take his dying adoptive mother's wealth — and finds the island's oldest fear waiting for him. The film draws its title, and its dread, from a belief that has circulated across eastern Indonesia for generations: the suanggi.
What the Suanggi Is Supposed to Be
Suanggi isn't a single monster with a fixed shape the way a vampire or a werewolf is. It's closer to a category — a person, usually a neighbor or even a relative, who has taken up a form of black magic so severe that they've stopped being fully human. Accounts of the belief come from Maluku, North Maluku, parts of Papua, Flores, and Sulawesi, each with its own local name and details, but the throughline is consistent: the suanggi causes illness, death, and misfortune that has no other visible explanation.
Two features recur across the tradition. The first is the hunger. A suanggi is said to need human liver — not the heart, which is the detail Dutch colonial writers tended to record, likely because European folklore treats the heart as the seat of the self. In much of Indonesia, that role belongs to the liver instead, so the substitution wasn't confusion so much as a translation problem between two different maps of the body.
The second is the disguise. A suanggi is described as able to shift into animals — cats, dogs, pigs, birds — or even travel as a floating ball of fire, moving through a village unseen until it's too late. Unlike the witch of European folklore, the suanggi isn't gendered as female by default; men are just as often named as suspects. What marks someone as a suanggi in the stories isn't appearance but behavior — a reputation for envy, isolation, or unexplained luck at other people's expense.
A Belief That Never Fully Left
This isn't only a story people tell about the past. Anthropological fieldwork in parts of Papua and the Maluku islands has documented suanggi accusations continuing into recent decades, sometimes tied to unexplained deaths in a village and sometimes to older grudges that finally found an outlet. Colonial-era records from the Dutch East Indies period already describe suanggi trials and killings in Maluku, which means the belief has had centuries, not decades, to embed itself in how some communities explain sudden loss.
Skeptical researchers point out what's missing from these accounts: no body has ever shown the surgical signature of an extracted liver, no physical evidence has turned up that can't be explained by ordinary disease or accident. The pattern researchers do find is social rather than supernatural — accusations tend to land on people who are already marginal in some way: the elderly, the isolated, someone recently on the losing end of a land or inheritance dispute. That doesn't make the fear less real to the people living inside it. It means the suanggi functions, in practice, the way accusations of witchcraft have functioned in societies across the world: as an explanation for suffering that also happens to sort out who gets blamed for it.
The Film Behind the Legend
Suanggi: Ilmu Kutukan leans directly into that regional specificity rather than generic horror imagery. Setting the story in Papua-adjacent eastern Indonesia, with a plot built around inherited debt, a dying matriarch, and a homecoming nobody quite wanted, the film uses the suanggi less as a jump-scare device and more as a manifestation of what happens when family obligation curdles into something else. That's consistent with how the belief tends to work in the source material — the suanggi is rarely a stranger. It's usually someone the village already knew.
Suanggi Among the World's Shapeshifting Witches
Indonesia isn't alone in imagining a human neighbor who becomes something else at night. In Morocco and parts of North and East Africa, the same fear shows up as the bouda, the hyena-shapeshifter — traditionally blamed on blacksmiths and, in a darker historical turn, weaponized against Ethiopia's Beta Israel community. In the Philippines, the aswang carries a strikingly similar profile: a person who looks ordinary by day and hunts by night, often through shapeshifting, often targeting the vulnerable. Across all three traditions, the pattern is the same — the monster wears a familiar face, and the fear does social work that has nothing to do with the supernatural claim on its surface.
FAQ
Is Suanggi a real Indonesian belief, or was it invented for the movie?
The belief predates the film by centuries. Suanggi appears in Dutch colonial-era records from Maluku and in anthropological research on Papua and the surrounding islands; the 2026 film borrows the name and the core fear rather than inventing them.
Does the Suanggi actually eat hearts or livers?
Regional accounts specify the liver, which is widely regarded across Indonesia as the body's emotional and vital center. Early European observers, working from their own framework where the heart holds that role, often mistranslated the detail as “heart” instead.
Is Suanggi always a woman, like a Western witch?
No. Unlike the stereotypical Western witch, suanggi accusations in the source folklore fall on men and women alike. What marks a suspect is reputation and behavior, not gender.
When does Suanggi: Ilmu Kutukan release, and who directed it?
The film is directed by Dom Dharmo and is scheduled for release in Indonesian theaters on September 10, 2026.
