The past isn't so easily buried. And William Afton's past is no exception. The children have all come back to play, forever. But in this twisted world, they're all the play things of the one pulling the strings, the One He Shouldn't have killed. William will have to monitor cameras, wind music boxes, reset vents, buy plushies, and check ducts to put it mildly in order to survive. All while staying in Hell and in the clutches of a vengeful spirit. But, there is one last twist to this already warped story, one that is sure to cause confusion.
