Back in 1982, located at the popping Freddy Fazbear Pizza! A younge girl, that goes with the name Charlotte Emily was staring at the stage where the animatronics were behined those red curtains. She did this whenever she went, as she felt like no one liked her. But that day, she saw a boy being lured into the backroom by the restaurant's founder and serial killer, William Afton. Despite her pleas for assistance being ignored by the adults present, she ventures into the back and sees Afton attempting to murder the boy. But she stopped it, saving the boy for the exchange of her own life.

Mike and Abby been living a good life. Mike used to be the security guard at the Freddy’s Pizzeria where the original’s were being placed. But after Bonnie, Chica, Foxy and Freddy teamed up on William Afton, that died in the springlock suits. Mike, not Abby knew what happened to the four and uncharted that was being possessed by kid souls. As back in 1985, when Willis Afton used to lure little kids in the back and kill them. He stuffed them and the only place he knew people wouldn’t check - Inside the animatronics. A little did he know the four kids souls would possessed animatronics. Abby always wants to see where friends, as the animatronics are still kids trapped in an oversized bunny, oversized bear, oversize chicken, and an oversize fox an Abby grow a strong relationship with him. But Mike didn’t know what happened to them, so we always use the same excuse that they were broken and he needs to repair them.

Venessa, suffers psychological trauma her dad, William Afton. She made a full recovery ever since what happened in the first Freddy’s pizzeria.

Mike found a poster that calling a number to learn about the kids missing on the previous Freddy Fazbear’s pizzeria. Out of curiosity, he took the paper and called the number. On the other line will appeared as Charlotte‘s father. They meet in person at Charlotte’s father, who is named Henry. But as Mike looked at the pictures, he noticed that certain details like a river was in the pizzeria they were talking about. Where he were the security guard at the original Freddy Fazbear’s pizzeria there was no river. And he know that Abby been talking a lot about meeting Chica, Freddy and Bonnie.

Venessa was on her way to the second Freddy’s Fazbear pizzeria. Knowing that Abby is there and the Puppet, who is now possessed by Charlotte. Who had been awoken by trespassers, who turned off her music box that kept her asleep. Now that Charlotte is awake, she want revenge on all parents for ignoring her on that day, leading to her death.

Venessa had a one-on-one conversation with Charlotte, where Charlotte threatened Venessa to tell the password for the security lock that prevents the animatronics from leaving the pizzeria. Or else she will have the Chica, Bonnie and Freddy kill Abby. As these animatronics are not the originals, they’re not possessed by children’s souls that Abby be friended but Charlotte. So Venessa had no choice. Mike arrived, finding Venessa. Mike stayed at the security office, tracking each of the animatronics. I assume they learned that they were outmatch. But Mike had a plan, he went to the original Freddy Fazbear’s pizzeria. Where he pleaded the unknown, and original Foxy, Chica, Bonnie and Freddy to help him, to her Abby. Before leaving to his house. Placed at his house, they were outmatched. Venessa’s brother, Michael Afton is just as evil as his father. Toy Bonnie, Chica, Fred’s and Mangel surrounds them. They were outmatched, but suddenly Foxy appeared, killing Toy Bonnie. Bonnie came, killing Mangel. Freddy came, killing Toy Freddy. And Chica came, killing Toy Chica. Michale, knowing his outmatched ran. Abby, despite the earlier situation was happy to see her friends. But suddenly, Foxy, Chica, Bonnie, and Freddy’s system begins to fail. As they were never meant to leave Freddy’s.

Abby: “W-What’s happening to them?!”

Mike: “I… I don’t know…”

Venessa: “Their system are failing, they warrant me at to leave Freddy’s…”

Mike: “Is there a way we can help them…?”
