Jade is one class away from graduating high-school, but that's one class she keeps failing: local history. Dragged down by her past, her father, and being an outsider, she's composing her epic essay series to save her high-school diploma. Jade's topic? The unifying theory of slasher films. In her rapidly gentrifying rural lake town, Jade sees the pattern in recent events that only her encyclopedic knowledge of horror cinema could have prepared her for. And with the arrival of the Final Girl, Letha Mondragon, she's convinced an irreversible sequence of events has been set into motion.

As tourists start to go missing, and the tension grows between her community and the celebrity newcomers building their mansions on the other side of the Indian Lake, Jade prepares for the killer to rise. She dives deep into the town's history, the tragic deaths that occurred at camp years ago, the missing tourists no one is even sure exist, and the murders starting to happen, searching for the answer. As the small and peaceful town heads towards catastrophe, it all must come to a head on 4th July, when the town all gathers on the water, where luxury yachts compete with canoes and inflatables, and the final showdown between rich and poor, past and present, townsfolk and celebrities, slasher and Final Girl.
