On a desolate country road, they encounter a menacing truck that aggressively tailgates them before speeding past. Soon after, they see the same truck parked next to an old church, where they witness a mysterious figure dumping what appears to be bodies wrapped in sheets down a chute. Their curiosity gets the better of them, and Darry decides to investigate the chute, leading him to a horrifying discovery that plunges them into a nightmarish ordeal.

As they escape, they seek help at a local diner, but their pleas are initially met with skepticism.

Struggling to survive, Trish and Darry face increasingly supernatural threats linked to ancient legends, realizing they have become targets of an unstoppable entity. Their race against time forces them to confront not only the creature hunting them but also their own fears and limits, as they desperately search for a way to escape the unrelenting terror.
