Jakarta, September 2026 — What if the scariest thing in a horror movie isn’t a ghost?

That is the unsettling question at the heart of Hasut, a mystery horror film from Tuta Films that builds its terror without relying on supernatural apparitions. Instead, the film draws fear from mysterious voices, growing suspicion, and the fragile bonds between four close friends as their trust slowly begins to unravel.

The concept takes center stage in the film’s official teaser trailer and teaser poster, offering audiences a glimpse of a psychological thriller where fear comes from uncertainty—and from the possibility that the people closest to you may not be telling the truth.

Hasut also marks the directorial debut of Ilya Sigma, who was previously known for her work as a writer.

When Healing Turns Into Control

The story follows four friends, played by Karina Salim, Rachel Amanda, Marthino Lio, and Kevin Ardilova, who travel to a remote forest area to take part in a meditation session as part of their journey toward self-healing.

At first, the trip is meant to be an opportunity for the four friends to support one another. But what begins as an attempt to heal gradually takes a darker turn, as care and concern begin to blur into control.

Then, mysterious voices begin to emerge.

The unsettling sounds fuel suspicion among the group, slowly driving a wedge between the four friends. As tensions rise, they begin questioning not only one another, but also their own perceptions.

What is actually happening? And what is merely the product of fear and suspicion?

As each character starts to trust only what aligns with their own beliefs, the line between reality and assumption becomes increasingly difficult to distinguish.

Rather than introducing a conventional ghost as the source of terror, Hasut turns doubt, distrust, and human psychology into its primary weapons.

Fear Without a Ghost

For Karina Salim, one of the film’s most compelling elements is precisely its decision to keep the horror grounded in atmosphere rather than relying on a visible supernatural figure.“What makes Hasut interesting is how the film creates fear without showing a ghost,” Karina Salim said in an official statement.

She also highlighted the use of sounds from communication devices such as handheld radios, which play an important role in creating the film’s eerie atmosphere.

The film’s focus on healing in nature also resonates with Karina’s familiarity with the wellness world, giving the story an additional layer beyond its horror premise.

A Personal Story for Ilya Sigma

For director Ilya Sigma, Hasut is more than a horror story. The film carries a deeply personal connection to her own perspective on emotional wounds, trust, and the desire to heal the people we love.“Hasut feels personal to me because it talks about wounds, trust, and the desire to heal someone we care about,” Ilya said in an official statement.

The film also explores a deceptively simple but complicated question: Where does caring end and control begin?

That question becomes increasingly important as the four friends’ journey progresses and their original intention to help one another begins to take an unexpected direction.

Much of the production took place outdoors, including in forest locations. Despite the challenges of filming in natural environments, the production reportedly proceeded smoothly, with no major difficulties affecting the cast or crew.

One Poster, Three Unconscious Bodies, and a Mystery

The teaser poster adds another layer of intrigue.

It features Rachel Amanda, Marthino Lio, and Kevin Ardilova appearing limp or unconscious, while Karina Salim is the only character shown still awake.

The striking image immediately raises a question: What happened to the other three?

Whether the answer lies in something supernatural, psychological, or entirely human remains one of the mysteries Hasut is keeping under wraps.

Produced by Tuta Films, with Putrama Tuta and Siera Tamihardja serving as producers, Hasut is set to arrive in Indonesian cinemas on October 8, 2026.

With its emphasis on psychological tension, mysterious voices, fractured trust, and the darker side of the healing process, Hasut promises a different kind of horror—one where the most frightening thing may not be what is hiding in the forest, but what happens when you can no longer trust the people beside you.
