Upon being hired, Jeremy is informed by Phone Guy of the details of his new occupation, also learning that the guard before him was moved to the day shift due to the animatronics trying to get into The Office.
Over the course of his shift, Jeremy learns that someone tampered with the animatronics, eventually leading to the restaurant's closing, and that he may be moved to the day shift as the "position just became...available" while the company tries to find someone to cover the night shift.
During Night 6, Phone Guy tells Jeremy that the next day he will work the day shift and is to closely monitor the animatronics during a birthday party. Upon completing the night, Jeremy receives a check for $20.10 for overtime, as well as a newsletter that says the restaurant is closing.
