Sofía, a young and somewhat insecure woman, embarks on her first job as a nanny for a wealthy family. She is tasked with taking care of two mischievous and demanding children who seem to be well-adjusted but carry a dark undercurrent of behavior that Sofía finds unsettling from the start. When their parents leave for an extended business trip, leaving Sofía alone with the children, she quickly realizes that things are not as they seem. The kids, initially appearing charming and clever, begin to exhibit strange behaviors that hint at a darker presence. They whisper in corners of the house where Sofía can't see them, giggling maniacally when no one else is around, and playing games with rules and objectives that defy logic and morality. One night, as she tucks them into bed, an eerie silence falls over the household. Suddenly, a demonic entity becomes manifest, its presence palpable in the form of shadowy figures and faint whispers. This entity is not just a malevolent spirit; it's fixated on playing children’s games with these innocent victims. As the nights turn into days, Sofía finds herself trapped in a nightmarish scenario where she must protect the children from their own twisted imaginations, all while unraveling the mystery of why this demonic force chose them. The line between reality and the supernatural begins to blur, and Sofía's struggle is not just for her own safety but also to save the two children who are now unknowingly caught in a game they cannot win. This expansion delves deeper into the psychological and emotional turmoil faced by Sofía as she navigates this terrifying situation, exploring themes of trust, fear, and the dark aspects of human (and non-human) nature.
