Three years have passed since the world was decimated by terrifying creatures known only as Reapers—indestructible, insect-like predators that emerged from underground sinkholes and wiped out about 95% of humanity . Out of necessity, the survivors have retreated to high-altitude sanctuaries perched above 8,000 feet—haven places like Lost Gulch Refuge in Colorado’s Front Range—where the Reapers inexplicably cannot reach them .

In one such mountain town lives Will, a devoted and desperate single father caring for his son Hunter, who suffers from a severe lung condition. Hunter’s oxygen filters are running out—a dire situation that forces Will to risk everything by planning a dangerous journey below the safety line to Boulder, where essential medical supplies might still be found.

Accompanying Will on this perilous trek are two women whose strengths complement his own: Nina, a brilliant but troubled scientist who may hold the key to defeating the Reapers, and Katie, a tough family friend determined to help no matter the danger. As they descend, they must traverse abandoned hospitals, ski lifts, and old mines, clinging to life at every turn.

Throughout their journey, they face horrific close encounters with the Reapers, which can detect humans by sensing their carbon dioxide output . Using ingenuity and courage, the group evades death multiple times: from activating backup generators to escape via ski lift, to employing magnesium-laced bullets theorized to breach the Reapers’ armored exteriors .

The climax comes when Nina’s groundbreaking theory proves true—cobalt-bullets cause Reapers to combust internally, exposing their mechanical, alien nature and giving humanity a fighting chance. Reinvigorated, the survivors signal neighboring communities with hope, their radio networks restored, and resistance bolstered.

Though the film plays out within familiar post-apocalyptic and monster movie tropes, critics note its strong performances—especially from Anthony Mackie and Morena Baccarin—alongside gripping cinematography and suspenseful tension. Sweeping Colorado landscapes and intimate, character-driven drama provide compelling context to the fight for survival.

In the end, Elevation isn’t just about monsters or survival—it’s about resilience and hope in the face of extinction. While it may tread well-worn narrative paths, its emotional core, stunning visuals, and glimpse at human ingenuity make it a worthy thrill for genre fans and a suitable setup for what may come next.
