Horror in the High Desert

The film opens by reconstructing the events leading up to Gary Hinge's disappearance in July 2017 in the Great Basin Desert of Nevada. It establishes Gary's plan to hike from Ruth to a cabin he had visited on a prior expedition and his expectation to return within a set timeframe. As days pass without word, the urgency of the case begins to mount.

Gary set out along a route from the small town of Ruth to a cabin he had visited on a prior expedition, studying his map and supplies. He usually traveled light and with limited provisions, which investigators cite as a risk factor in a harsh desert environment. The plan provided the backbone for the early search, anchoring expectations for a quick return.

When Gary failed to return two days after his anticipated arrival, his housemate Simon Rodgers alerted Beverly Hinge, who promptly notified authorities. The initial concern centers on a missing-person lead rather than an obvious crime. The clock begins ticking as friends and family rally to the search.

Local and state police, park rangers, and volunteers begin a formal search based on the last GPS location from Gary's phone. They comb desert terrain with on-foot teams, helicopters, and drones, expanding the area as days pass. The early efforts yield little more than dusty footprints and heat near the trail Gary had followed.

A breakthrough occurs when Gary's truck is located 55 miles from Ruth at the end of a dirt road at the base of a small hill. The discovery shifts investigators' attention to the vehicle as a potential crime scene. Search teams then widen their sweep around the truck's location.

Despite aerial support and extensive on-the-ground efforts, no sign of Gary materializes beyond the truck. Helicopters, drones, and ground teams search the surrounding terrain for days. The lack of evidence begins to cast doubt on a recovery while the harsh environment takes its toll on morale.

Officials acknowledge the slim likelihood of locating Gary alive, citing peak-summer heat, scarce supplies, and treacherous terrain. The case shifts toward a missing-person investigation and later a potential crime scenario. Media attention starts to fade as resources are redirected.

Beverly Hinge hires private investigator Bill Salerno to pursue leads beyond the official inquiry. Meanwhile, local reporter Gal Roberts pushes for continued media coverage to prevent the case from going cold. The decision to bring in private help marks a turning point in how the case is explored.

Forensic analysis of Gary's abandoned truck reveals an array of unidentified fingerprints on the steering wheel and a trail of barefoot footprints not matching Gary. Investigators struggle to connect the prints to any known individual, stalling the official inquiry. The truck's clues point to a deeper mystery beyond a simple disappearance.

Salerno uncovers Gary's online presence under the pseudonym 'Scorpion Sam', revealing about 50,000 followers on his survival blog. One late video recounts a three-day hike where he detects smoke, finds a seemingly abandoned cabin with an active chimney, and camps at a distance, sensing danger. In another post, he mentions being followed, prompting skepticism and commentary from his audience.

In a final emotionally charged video, Gary says he won't disclose the exact cabin location, fearing inexperienced hikers would wander into danger. He promises to return with extra equipment, including a video camera and a firearm for protection. The video reveals his escalating concern and determination as he prepares for a risky return.

Weeks after the truck's discovery, hikers in White Pine County find a backpack at their campsite containing Gary's severed hand clutching his video camera. Forensic analysis dates the severing to within five weeks of discovery, suggesting Gary was alive for a period after the truck went missing. The discovery reopens questions about Gary's fate and triggers deeper investigation into the crime scene.

The memory card from Gary's camera shows footage of his final night at the mysterious cabin, fueling extensive speculation and conspiracy theories. The footage is interpreted by some as evidence of dangerous encounters, while others cite possible external influences from government tests, cults, or extraterrestrial activity. The film ends by leaving the true explanation ambiguous.
