Story without spoilers

After her father dies suddenly by the Ciliwung River, Aci becomes convinced that a supernatural entity known as the Ciliwung Spirit took his life. She responds by vowing revenge, while her mother repeatedly argues that asthma was the real cause of death.

As Aci’s fear and anger intensify, her mother grows exhausted by the escalating situation. In a reckless attempt to confront the belief directly, she summons the entity, setting the central conflict in motion without revealing how it ends.

What to expect

Seethe is a compact horror story built around grief, conflicting explanations and a supernatural threat connected to the Ciliwung River. Its short 17-minute runtime points to a focused narrative rather than an expansive mythology. The premise also places the emotional tension between Aci and her mother alongside the question of whether the danger is spiritual, physical or both.
