Widia (Salsabila Zahra), Ilham (Robert Chaniago), Raisa (Tania Qumsoani), and Alil (Peter Valentino) are four friends who must submit their thesis topics soon. An antique dealer suggests they research a sacred jailangkung, which is said to help people resolve past conflicts. Torn between skepticism and curiosity, they begin performing a ritual to summon spirits. Unexpectedly, their decision to choose the jailangkung as their thesis topic traps them in a supernatural disaster that reawakens trauma and threatens their lives.
