The movie is set in the Conjuring Universe, serving as its sixth entry.
When Anna Garcia, a social worker and widow raising her two children in 1970s Los Angeles, is called to check in on one of her cases, she finds signs of foul play. As she digs deeper, she finds striking similarities between the case and the terrifying supernatural occurrences haunting her family. Enlisting the help of a local faith healer, she discovers that La Llorona has latched herself onto Anna and will stop at nothing to take her children. La Llorona, also known as the Weeping Woman, is a female ghost in Latin American folklore who lost her children and causes misfortune to those nearby. As she searches for them, she takes other lost children, making them her own. Anna turns to mysticism with the help of a disillusioned priest to fight the evil entity.
Good horror movie
