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.

Two exorcist priests, Romo Thomas and Romo Rendra, must confront an immensely powerful entity of darkness: the demon Rephaim, born from an ancestral blood covenant. The gripping terror begins when a failed ritual in a remote town in Indonesia unleashes chaos, forcing the church to perform an exorcism to save the souls possessed as a result of a pact for wealth (pesugihan).
