At Grace Field House, the orphans enjoy an idyllic life! Despite lacking parents, they form a close-knit, joyful family with the other children and their caring “Mama.” Every child is guaranteed adoption by the age of 12, ensuring none are left behind. Their routine includes challenging tests, but they are rewarded with outdoor playtime. However, they must adhere to one crucial rule: never leave the orphanage. One day, two of the brightest orphans, Emma and Norman, cross the boundary and discover the terrifying truth about their lives: they are merely livestock, and the orphanage is a farm designed to produce food for a mysterious demon race. With only a few months to devise an escape, the children must find a way to alter their destined future.
