Watch on SFlix. 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.
