Little Sadie never knew the secret behind Freddy Fazbear's Pizzeria. She always thought the animatronics were the friendliest things she'd met since birth. But then came the bite. The Bite of '87. Little Sadie didn't understand why he did it, why he hurt that poor little girl. Sadie continued to visit Freddy Fazbear's Pizzeria, until her mother noticed red liquid coming from Freddy's eyes. After that, Sadie's mother never let her visit the animatronics again. On August 14th, 1999, 17 year old Sadie signed up to help Freddy Fazbear's Pizzeria. She was in charge of cleaning. As soon as the pen touched the contract, her whole life began to change.

It's about this 17-year-old guy named Ethan Stinson who was being nagged by his mom for a job. so his mom gave a recommendation to look on the daily newspaper she picked up and it had a big ad for Freddy's Pizzeria as they were looking for a bodyguard. With no hesitation, he went and got it. It started at midnight and ended in the morning, but something wasn't right... Before the owner left for the night, he left the animatronic machines on free roam and they stayed like that for the whole night. As Ethan looked through to the security cameras, some of them were gone of the stage and he seen the bunny mouth covered in blood, staring ahead. He looked closer and the bunny eyes slowly looked up at the camera and smiled, making Ethan fall out of his seat and heard a Deep laugh down the hall... What hellish nightmare did he get into?!
