A girl named Emma begins to chronicle the basics of her life by presenting the Orphanage Grace Field House as her home, Mama Isabella as her "mother", and the children there as her siblings. Showing her scene waking up and waking up the other children, Emma says they should wake up at 6 o'clock sharp with a bell ringing. She helps the younger kids straighten up and runs into the dining room, where two kids slap their backs, who were playing catch. Emma says she will eat them and runs after them. She enters the kitchen, where Ray and Norman are greeted. Ray asks if she is 5 because of her pranks, irritating her, which reminds her that both are 11 years old. Mama calls her, frightening Emma at first, who thinks that she would receive a scolding from her. She cries and says that she will do everything as an adult, but Mama says that she loves his attentive and affectionate side, leaning her forehead on hers, cheering Emma up. Emma narrates that she loved them and considered them her family, even though they had no blood ties, and that this was her home, while they were shown eating.
After lunch, everyone begins to take the intelligence test, which Emma comments on happening daily to replace a conventional school. After 60 questions with 10 seconds each, Mama announces that Emma, Ray and Norman took the perfect scores, 300. She congratulates Emma affectionately, who comments that Mama's compliments were worth the effort of the tests. The children go out into the yard and decide to play catch-all, where Norman is the one to pick. He begins to count and all flee into the forest. As she runs through the forest, Emma sees the gate. It is the only forbidden place to go, the place that gave way to the outside world, which they have never seen. Emma remembers when she, Norman, and Ray went to the gate secretly when they were children, but did not go through it when remembering the order of Mama.
Near the house, Gilda complains that she has not received any letters from her adopted brethren, saying that now that they are living well, they have forgotten them, wanting to leave the orphanage soon to wear various clothes. Emma comments that what they know in the outside world is through books, magazines, and research. Not far from there, Don was astonished to find that almost everyone had been caught by Norman, but now Emma was missing. After much persistence, Norman manages to get her, Emma asks how good he is, although he has never beaten her in a race. Ray says that Norman had tactics, explaining that he watches as the target moves and thinks about how he should attack as if it were a high-level chess game.
Norman appears and asks if it was not what made the game fun, taking advantage to say that he thought Ray a better strategist than him, causing distrust in him to be praising much. By far the other children admire the intelligence and agility of Emma, Norman, and Ray. Don goes to Norman and says he will have a revenge, proposing that this time be against Norman, he agrees, saying he would not get caught. Don says that he will regret his words by telling Conny that they would catch him by making Emma remember that this was the girl's last day.
At dusk, the orphans all came to bade farewell for Conny. Having her stuff animal next to her, Conny tried to cheer her brooding siblings up and modestly explained how she is average compared to her older siblings. After Conny leaves, Emma is thoughtful, remembering the sad farewells of the last 10 years, thinking that the next one to leave is either Norman or Ray. Emma then walks into the kitchen and finds Bernie, startled by Conny's carelessness, But could not return it. Emma, alongside Norman, took the stuff animal and proceeded to go find Conny.
Reaching the dark exit of the orphanage, Emma and Norman searched every nook and cranny of the place. As Emma scanned through a section of a truck, Emma was frightened to her wits, as she discovered a corpse which turns up to be Conny's. Both Emma and Norman were traumatized at the sight of their deceased sibling, as they forged to hide under the deck of the truck when a dark figure approached into the vicinity. Shocked and frightened by the giant figure, Norman and Emma gasped at their first sight of seeing a demon. And even more so when they discovered that their own guardian had been working with the demons behind their back. As the demons placed Conny's corpse into a jar as preparations for the Gupna Ritual, Norman and Emma run toward the orphanage. As they reached a safe distance away from the exit, a devastated Emma collapsed onto the ground, as she recalled the sighting of her sibling's death and Isabella's betrayal. Questioning an equally distraught Norman on how are they going to survive, Norman patted Emma and consoled her.
Gupna hands Mama the rabbit Little Bunny, who he found under the truck, ordering her to throw it away. Returning to the scene where Emma is comforted by Norman, she says that everything has changed after that, Norman tells them to flee from there, even though he knows nothing of the outside world, keeping in mind that they and Ray may be next. Emma, crying, asks if it is possible to take the children, not supporting them to die that way, he smiles at her and says they will be able to get away with everyone. Returning to Emma in her bedroom, she says she does not want to cry anymore, thinking that to escape from there, tactics like the tag game were necessary so that they could all survive.
