After a group of would-be criminals kidnap the 12-year-old ballerina daughter of a powerful underworld figure, all they have to do to collect a $50 million ransom is watch the girl overnight. In an isolated mansion, the captors start to dwindle, one by one, and they discover, to their mounting horror, that they’re locked inside with no normal little girl.

Two sisters find an ancient vinyl that gives birth to bloodthirsty demons that run amok in a Los Angeles apartment building and thrusts them into a primal battle for survival as they face the most nightmarish version of family imaginable.
