Emma, Norman, Ray and the other orphans at Grace Field House live peaceful and happy lives. When one of the orphans is adopted and forgets her favorite toy, Emma and Norman attempt to return it to her only to discover a horrifying truth.

Emma and Norman begin making plans to escape the House. As they plan, they become suspicious of Isabella’s behavior and actions.

Krone arrives at the House to assist Isabella with watching the children. Krone, however, develops her own agenda. Later, Emma, Norman, and Ray begin to "train" the other children to prepare them for escaping the House.

Emma, Norman and Ray suspect that there’s a traitor among the kids providing information to Isabella. They decide they want to tell Don and Gilda the secret of the House, while suspecting that one of them could possibly be the traitor.

Norman discovers Ray is the traitor and Isabella’s informant and confronts him about where his loyalties lie.

As preparations for escaping the House continue, Emma shares a discovery with Norman and Ray. Meanwhile, Don and Gilda search through Isabella’s secret room.

Krone discovers which children are aware of the House’s secret. But rather than alert Isabella, Krone proposes an alliance with Norman, Emma and the others to help meet each other’s goals.

Krone receives a letter from the Grace Field headquarters and departs from the House. Later on, Emma and Norman go to inspect the wall surrounding the House while Ray attempts to distract Isabella.

As Emma steps down from moving the escape plan forward, a new shipment date is announced earlier than expected, and someone will get shipped before Ray.

Emma loses yet another ally and friend, and in the brink of despair, Mom pays her a visit in the infirmary.

Ray and Emma haven’t spoken to each other for nearly two months. With Ray’s shipment approaching, have they really given up? In the midst of despair, Emma finds Ray in the library.

As Emma and Norman continue to surprise Ray, the fated night finally arrives. As Phil holds on to Mom, what will he say?

Emma and the children have finally escaped the House and now head to the place indicated on the pen Norman gave them. But on their way, a large, wild demon attacks the group…

The children’s saviors turn out to be demons named Mujika and Sonju. The pair claims that their religion forbids them from eating humans. Emma and Ray visit Sonju while the others are sleeping in order to find out what happened to humans thirty years ago.

Emma and the group learn the necessary skills to survive in this world from Mujika and Sonju. Back on their own, the children traverse a wasteland in search of a place called “B06-32.”

Without warning, the shelter’s phone begins to ring, echoing through the halls. Emma hesitantly answers and finds that it is William Minerva. Meanwhile, in an underground room at the farm headquarters, a deal is made…

Emma and the other escapees manage to survive the attack on the shelter. Now they have settled in an abandoned temple a short ways from a demon town. Unlike the shelter and Grace Field House, here there is a limited supply of food, and they are barely surviving.

Norman, thought to have been shipped, stands before Emma and Ray. It is a reunion they never dreamed of, and they embrace tearfully. Norman reveals his plan to create the future Emma wants, where the children can live happily.

Though Emma pleads with him, explaining she has no wish to eradicate the demons, Norman is set in his decision and deaf to her arguments. To resolve their dispute, Emma proposes a deal.

Norman, seized by a terrible fit of coughing, spits up blood. He lied about not being experimented on when he was at Lambda. With the little time he has left, Norman manages to reunite with Emma and hopes to create a world where she and the children can live in peace.

Norman has begun executing his plan without waiting for Emma. When Emma, Ray, and Sonju appear, Norman is hesitating to kill Vylk and his grandchild, but he tells them that they are too late and that the plan is already in motion.

Vincent reveals his plan to enter the farm. After hearing this plan, Peter reconfigures the security on the farm to prepare for the intruders. Meanwhile, the shipment of children from the house has been set in motion, and Phil has already arrived at the gate.

As Emma extends her hand to Peter and says, "Let's be free," he shows a calm expression, but realizes his true fate. The children finally arrive at the gate leading to the human world, where they hope to pass through.
