In the tranquil Grace Field House, Emma, Norman, and Ray lead a seemingly idyllic existence alongside thirty-five other children. Under the watchful care of Isabella, or "Mom," their days are filled with laughter, games, and intellectual tests that showcase their remarkable genius. Their world is confined to sprawling green fields and a surrounding forest, with only a flimsy fence marking its periphery. It seems like a perfect life, until an innocent event begins to unravel their secure world. Connie, one of the younger children, is adopted and says a tearful goodbye. But when Emma and Norman rush to return Connie’s forgotten stuffed bunny, they discover a chilling scene: Connie's lifeless body packed in a truck, revealing the horrifying purpose of their lives—they are being raised as livestock for demons.
