At Grace Field House, children leave for adoption every few months, but none ever sends word back. The three oldest children have begun to question what is happening at the orphanage, despite the happy life they share with the other orphans and their beloved caretaker, Isabella.
Known to the children as Mama, Isabella looks after them as one large family. Daily tests punctuate their otherwise carefree routine, and they can play outside provided they never stray too far from the orphanage. Behind this familiar life lies a cruel fate awaiting the children. As the oldest three uncover the truth, they will also discover a disturbing side to the woman they trust.
