Premise: Life is peaceful for Emma, Norman and Ray, three children of a special orphanage directed by Isabella, a sweet woman they all call "Mom". In this house surrounded by a large playground and a forest, children of all origins are raised with love and care, the only constraints being the regular tests of knowledge that establish a ranking by score, and the forbidding to go near the main gate or beyond the forest. Every child is eventually sent away to a foster family, sooner or later, but always before their twelfth birthday.
Being 11 and the top-ranked children of the orphanage, our protagonists know they will be the next to leave after the little Conny. But while they thought they would see her off, they witness something they shouldn't have and discover with horror what kind of "foster family" the children are sent to... Now that they know the truth, they will have to find a way to escape from the house and save its children before they turn into the next dish on the menu. But their once-beloved Mom doesn't intend to make their mission any easier. A battle of wits soon engages.
