Cult Girls (2019) on Netflix

Plot summary

Dalia and her two younger sisters are raised inside a pagan cult that waits for the end of the world and follows an ancient Baltic goddess associated with death and rebirth. Police raid a major ceremony one night and carry Dalia to safety, while the members escape with her sisters. Years afterward, guilt over that night wears her down. A possible trail back to the cult opens through a black metal artist, prominent in his scene and widely disliked, who lives apart in the woods. Dalia leaves to find the sisters taken from her, and the trail leads her toward the cult and toward what became of them.
