After the fire that burned down Fazbear's Fright, there was nothing that could be done. Several months later, a new haunted house attraction is coming to take its place. The Springtrap from the old attraction was bought from a public auction and is now sitting inside alongside a ghost, a zombie, and Death himself. To make things even worse, you found the ad in the newspaper.
This is where the protagonist, Michelle Schmidt, works in The Fright Manor.
