In 2009, six university students—Nur, Widya, Ayu, Bima, Anton, and Wahyu—participated in a community service project (KKN) in a remote village in East Java.

While Nur and Widya are about to bathe, they are haunted by a black figure and a woman dressed in traditional Javanese dance attire.

Nur, who frequently experiences headaches since the KKN began, visits Mbah Buyut, the village shaman.

That same day, the joglo house where the students are staying is suddenly raided by villagers who inexplicably see Widya as a snake.

In response, Pak Prabu suggests they end their KKN activities, but Ayu insists they continue.

Bima confesses to Nur that on his first night in the village, he had a dream about a Javanese dancer named Dawu who wrapped Widya in a snake.

Mbah Buyut enters the spirit world called Angkoromurko, where Ayu is forced to dance by Badarawuhi, while Widya is prevented from leaving.

Four years later, Nur and Widya give an interview to a documentary filmmaker, with the condition that all names involved be disguised.

In a mid-credit scene, Nur visits a religious leader who tells her about Mbah Dok, the spirit of the old woman who followed and protected her.
