Three student filmmakers, Heather, Mike, and Josh, venture into the Black Hills near Burkittsville, Maryland, to create a documentary about the local legend of a witch responsible for the mysterious disappearances of several children. Armed with a video recorder and a 16mm camera, they conduct interviews with town residents, who share chilling tales of the so-called Blair Witch and past incidents tied to the supernatural folklore. Despite warnings, the trio eagerly embarks into the dense woods in search of more evidence and footage. Confident yet slightly apprehensive, they follow Heather’s map through the wooded trails, capturing their experiences as they delve deeper.

As they journey further into the forest, bizarre occurrences unsettle the group. They hear strange noises at night and discover eerie rock formations and figurine bundles left outside their tent, hinting at an unseen presence. Tensions rise as their navigation fails, leaving them lost and increasingly desperate. Mistrust and paranoia seep into their interactions, exacerbated by dwindling supplies and frayed nerves. Conflict escalates when they face unexplainable phenomena that shake their rational understanding of reality. Tethered by hope and the cameras documenting their every move, they are drawn into a harrowing plight that distorts the boundary between fear and existence.
