In a disturbing suburb, a young social worker named Ann is assigned to investigate a peculiar and unsettling case. The situation revolves around an adult man with the mentality of a baby, known as "Baby," who lives in a home where he is cared for by his possessive mother and his two unsettling sisters. As Ann becomes involved in the lives of this strange family, she quickly realizes that there is something very dark lurking beneath the surface.
The mother, a dominant figure, uses Baby as an object of affection and control, while the sisters, with their erratic behavior, create an oppressive and tense atmosphere. Drawn to both Baby's vulnerability and the family's strange dynamic, Ann becomes a mix of advocate and observer, trying to understand what is really happening in that house.
Over time, Ann discovers that the connection between Baby and his family is much murkier than it initially appeared. The lines between love, manipulation, and madness begin to blur, leading her to a shocking conclusion that will test not only her professionalism but also her sanity. In a plot that challenges norms and plays with emotions, the film explores the limits of familial devotion and what it truly means to be a "child." The unsettling atmosphere and the complex relationships between the characters keep the viewer on the edge of their seat.
