In 1981, a struggling family lives in an old house in rural Indonesia. The mother, Mawarni (Ayu Laksmi), was once a famous singer, but she has been bedridden for three years with a mysterious illness. Her eldest daughter, Rini (Tara Basro), cares for her and her younger brothers. When the mother dies, strange things start to happen.
Joko Anwar uses classic haunted-house scares: creaking doors, shadows in mirrors, a ghostly figure in the corridor, and an old record of the mother's song. But they are expertly timed, and some of the jump scares are among the best in modern horror.
The 1980s setting, the old house and the family's poverty give the story a strong sense of place. The young actors are excellent, especially Muhammad Adhiyat as the deaf youngest son, Ian.
The plot gets busy towards the end, and the mythology can be confusing. But Satan's Slaves is a genuinely terrifying ghost story and a must for horror fans.
