In a world where vulnerability is often mistaken for evil, a social worker named Emily Jenkins faces a case that will challenge not only her professionalism but also her perception of reality. Emily receives a call about a girl named Lilith, who lives in a situation of extreme abuse and fear. Upon her arrival, she realizes that the situation is worse than she imagined; the little girl seems to be the victim of an unhinged mother, filled with darkness and resentment.
Moved by Lilith's story, Emily decides to intervene and temporarily welcome her into her home. However, what should be an act of kindness quickly turns into a nightmare. As they attempt to create a new life together, Emily begins to notice strange occurrences around her, as if the innocent girl has a haunting shadow that follows her every step.
The young girl not only seems to possess a spell over those around her, but she also awakens a series of disturbing mysteries that lead Emily to question her own sanity. Forming an atmosphere of escalating desperation and chaos, Emily finds herself caught between the desire to protect Lilith and the growing evidence that perhaps the girl is not who she claims to be. Trapped in a game of psychological manipulations, Emily must fight for her life and the little one's, while uncovering a dark secret that has been hidden beneath a façade of innocence.
