For 19-year-old Jay (Maika Monroe), the fall should be about school, boys and weekends at the lake. Yet after a seemingly innocent sexual encounter she suddenly finds herself plagued by nightmarish visions; she can’t shake the sensation that someone, or something, is following her. As the threat closes in, Jay and her friends must somehow escape the horrors that are only a few steps behind.
