Pengabdi Setan

A family lives in an old house that once belonged to their grandmother, Rahma (Elly D. Luthan). The family includes the sickly mother, Mawarni (Ayu Laksmi), the father, Bahri (Bront Palarae), the eldest daughter, Rini (Tara Basro), and her three younger brothers, Tony (Endy Arfian), Bondi (Nasar Anuz), and Ian (Muhammad Adhiyat).

Mawarni's illness has put a financial strain on the family due to the high cost of her medical care. This has forced Bahri to work extra hard and Rini to drop out of college. Previously, the family had been well-off because Mawarni was a legendary singer known for her hit song "Kelam Malam."

At one point, Mawarni, who could only communicate by ringing bells, began acting oddly and eventually passed away. After her funeral, strange events started occurring in Grandma Rahma's house. Mawarni's spirit seemed to return, and other terrifying incidents began to haunt the family.

The situation reached its peak when Bahri, Rini, and their siblings witnessed undead creatures approaching their home. Upon further investigation, they discovered that Mawarni had been involved in a heretical cult and that Ian was a crucial member desired by the cult. Despite the overwhelming circumstances, Rini tried to find a logical solution to these mysteries and wanted to resolve the situation at any cost.
