The main character Mike Schmidt,has started a job working as a night watch security guard at the restaurant Freddy Fazbear's Pizza. A voice mail message left by Phone guy explains that the animations animal characters used at the restaurant, Freddy Fazbear, Bonnie, Chica and the disused Foxy, are able to roam freely around it at night. Says that the animatronics were no longer allowed to roam freely during the day following an incident referred to as the "Bite of '87", which apparently involved the loss of someone's frontal lobe. The employee warns Mike that if one of the robots encounters a human, they will automatically assume that it is an exoskeleton that is not in costume yet, and "forcefully stuff them" into a spare mechanical Freddy Fazbear costume, killing the person in the process. Newspaper clippings in the background of one of the scenes reveal that the restaurant was site to the disappearances of five children whose bodies were never found, after a man dressed as one of the animatronics lured them into a back room and reportedly murdered them. Later, the restaurant received complaints that the animatronics began to smell foul and became stained with blood and mucus around the eyes and mouth, with one customer comparing them to reanimated carcasses.
