Sumala (2024) Plot Summary & Ending Explained

In the final act the cursed twin Sumala reawakens, possessing her sister Kumala and turning the child into a vessel of the Devil’s vengeance. When the family’s desperate attempts to contain her fail, Sumala‑possessed Kumala murders Soedjiman’s right‑hand man and then attacks her mother, Lastri, who begs for mercy but is slashed as the spirit refuses to be released. Soedjiman arrives too late; his wife collapses, and he is forced to flee as the horror spreads through the house.

Desperate to end the possession, Soedjiman drags the unconscious Kumala into the fields, intending either to bring her to a shaman or to kill her. He cannot bring himself to stab his own daughter, so he covers her head with a sack. At that moment Sumala taunts him, condemning his cruelty and his own disabled past, and then the Devil’s child finishes him off—his body is disemboweled and hung on a pole, a grim echo of how he once chained Kumala.
