After losing his mother and sister, Thomas plans to resign as a priest but is tasked with assisting exorcist Rendra. Together, they confront demons possessing Kayla, his late sister's friend, while her mother Maya battles a haunting past.

A group of Indonesians: Juna, Adit, Bara, Arum, Yuri, and Tyas set out to live-stream a test of courage at the so-called most haunted hospital in South Korea, Yong-Won Hospital. Rumor has it that the hospital was once a front for a cult whose members chose to die following their leader. Now, the hospital is in a state of disrepair and no one dares to enter. This motivates Juna and his friends to become the first people to live-stream there.
