Two timelines. In 1973, Henry Stillwater — founder of Fredbear's — has lost his night guard without explanation and taken the shift himself. Working alongside Afton Robotics to build a family restaurant, he begins at night to see what the man behind the animatronics has really been doing. In 2017, paranormal investigator Max Donovan receives an anonymous tip about Henry Stillwater's sudden disappearance. He goes to the abandoned Fredbear's location to investigate — unaware that something restless is waiting there, and that it wants to show him everything.
