“You were warned. It was always watching.”

The Nahanni Valley in Canada’s remote Northwest Territories is a place of staggering beauty — endless pine forests, glacial rivers, and mountains that touch the clouds. But to the Dene and other Indigenous peoples, it is also a place of dread. They call it the Valley of Headless Men, a land haunted by stories passed through generations: tales of a guardian spirit, the Nakani, born from the bones of the earth and bound to defend it with unyielding fury. Those who trespass where they are not welcome rarely return. Those who do are never the same.

A group of adrenaline-chasing hikers arrives under the banner of adventure and internet fame, determined to document their trek into the valley’s heart. They laugh off the warnings, seeing them as quaint superstition. But the deeper they venture, the more the land begins to change around them — trails vanish, trees seem to shift when unobserved, and the wind carries whispers they cannot trace. Then the first body is found… headless.

Fear takes hold. Panic fractures their camaraderie. Into the chaos steps Grant Mercer (Dwayne “The Rock” Johnson), a hardened ex-military survivalist who thought he had seen every face of war and death. This is different. The enemy here is unseen, silent, and impossibly fast. Every instinct tells him that they are not merely lost — they are being herded.

Desperate, Mercer joins forces with Nate Colburn (Jason Statham), a solitary wilderness tracker who has scars — physical and otherwise — from a previous encounter with the valley’s terror. Nate knows the legends are not just stories; he has tracked the signs before: claw marks that strip bark to the bone, footprints that vanish mid-stride, and the gut-deep feeling of being watched.

Together, they uncover a chilling truth: the Nakani’s wrath has been unleashed because an ancient pact between the spirit and humankind was broken. The forest itself is its ally, the terrain shifting to confuse and trap its prey. Each night, the darkness grows heavier, the air thicker with dread. The killings are not random — they are ritual. And the Nakani does not merely kill; it takes.

As the survivors dwindle and the valley closes in like a living tomb, Mercer and Nate face an impossible choice: attempt a desperate escape through hostile, ever-changing terrain… or confront the ancient force head-on, knowing that no weapon forged by man may bring it down.

NAKANI is a chilling descent into survival horror — a tale of primal vengeance, Indigenous myth, and the brutal truth that in some places, nature is not yours to conquer. You don’t own this land. You don’t tame it. You survive it… if it lets you.
