In the small town of Greenfield, rumors swirl about the old Fredbear's Family Diner, a once-thriving restaurant known for its animatronic performers and family-friendly atmosphere. However, tragedy struck one fateful night, leading to the diner's abrupt closure and a shroud of mystery that lingers to this day.

You play as Alex, a curious teenager who becomes obsessed with uncovering the truth behind Fredbear's. After finding an old newspaper article about the diner's closure, Alex decides to explore the abandoned building, now a decrepit shell of its former self.

As Alex delves deeper into the diner's history, they uncover a dark secret: years ago, a series of unexplained incidents plagued the diner, culminating in the disappearance of several children. The town was horrified, and despite the best efforts of the authorities, the case remained unsolved.

Driven by a desire for answers, Alex discovers a hidden room in the diner's basement, where the animatronics were stored. There, they find clues suggesting that the animatronics may be more than just machines – they may be haunted by the spirits of the missing children, seeking vengeance for their untimely deaths.

As Alex tries to piece together the events of the past, they are haunted by the animatronics, which come to life at night and roam the diner's halls. Alex must survive five nights at Fredbear's, avoiding the animatronics and solving puzzles to uncover the truth before it's too late.
