There's a reason CJ Smith's hometown of Satterville, Ohio is infamously known as Slasherville: years ago, it was the site of not one, but two real-life Friday the 13th-style massacres. CJ's dad survived the first attack; only CJ survived the second. And thanks to the mysterious writer Moon Satter's two bestselling novels based on the events, the town-and CJ-will always be defined by its horrific past.
Then a third unpublished Moon Satter manuscript shows up addressed to CJ. But unlike the other two, it's not based on the past. Instead, this one predicts new murders.
Fortunately, CJ appears only as an extra (chances of survival: high). But what are they going to do, just stand by as their classmates get picked off one by one? On the morning that the manuscript predicts the first murder to occur, they set out to stop it. CJ succeeds in saving one classmate, but in her place, the story's intended final girl turns up dead. CJ and their friends have suddenly gone from extras to leads-and they're going to have to use everything they know about the rules of horror movies to make it out alive.
