A woman's happy marriage starts to unravel when her college-age sister moves into her home and draws the intention of her husband.

Najwa, a teacher from a small town, moves to Jakarta for the sake of her daughter Yanti’s future after accepting a teaching position at an elite school run by a foundation. However, their new home harbors both terror and clues from vengeful spirits—victims of an ancient cannibalistic practice carried out by the foundation's founders. As a deadly ritual draws near, Najwa must confront dark forces to save herself and her daughter from becoming the next sacrifices in the cannibalistic rite.
