When a young stranger visits Vernette, she is asked to recall the darkest moment of her life-the spiritual possession slowly overtaking her mind, leading to a gradual descent into madness. This descent drives her to do unspeakable things, even murder. Once a humble woman, jealousy consumed her from childhood, especially toward her younger sister, Veronica. As Vernette battles a malevolent force tied to a generational curse, she uncovers a haunting family secret.
