Synopsis: For 19-year-old Jay, fall should be about school, boys and weekends out at the lake. But after a seemingly innocent sexual encounter, she finds herself plagued by strange visions and the inescapable sense that someone, or something, is following her. Jay and her teenage friends must now find a way to escape the horrors that seem to be only a few steps behind in this critically-acclaimed chiller that Bloody Disgusting calls "the scariest movie of 2015."
