Plot
A plane carrying a small crew and Bio-Comp researcher Tara Knowles malfunctions and crashlands in the Canadian wilderness. The survivors encounter a monster that viciously attacks them. After several weeks of unsuccessful rescue missions, Harlan Knowles, Tara's father and a Bio-Comp executive, organizes his own rescue team: computer engineer Plazz, insurance representative Marla Lawson, survivalist Winston Burg, forensic investigator Nikki Adams, and local mountain man Clayton Tyne.
Arriving near the suspected crash site, they set up camp. At night, Marla is attacked by what Clayton determines was a grizzly bear. The next day, they come across the bear corpse, its neck broken by a nearby boulder. At sunset, a thunderstorm approaches, forcing the group to take refuge in a cave. They find drawings, which Nikki determines are made with blood, and only a few months old. Harlan finds a piece of Tara's necklace.
After another day of searching, they camp near a natural hot spring. Marla confronts Harlan in private. She knows Tara is in possession of a prototype for an important new project. If it is not retrieved, Bio-Comp is practically bankrupt. She offers to keep quiet in return for $30 million in Bio-Comp stock. Meanwhile, Clayton confronts Burg about the flaws he made while tracking, and calls into question the claims in Burg's survival books. An angry Burg threatens Clayton.
The following day, the group locates the crash site but only finds a piece of the fuselage. Following a conspicuous track, the group finds the plane wreck, hidden under thick foliage. They find a crewmember's a severed arm, still holding a pistol. Nearby, Burg finds "Huxley", the prototype. It is able to instantly analyze the genetic history and makeup of any organic material on Earth. Plazz powers on Huxley and finds it was used on some blood sample shortly after the crash. The machine shows the blood belongs to a Sasquatch.
That night, a drunken Burg hears a noise and randomly shoots into the forest, narrowly missing others. He hits a creature, which lets out a roar. Harlan fires Burg and promotes Clayton to their head guide. Infuriated, Burg feebly attacks Clayton but quickly gives up; the others leaving him alone at the campfire. Burg cries out as the Sasquatch grabs him. Harlan reviews tapes found in the fuselage and deduces the crash killed a Sasquatch, resulting in its family killing the crew in revenge. Clayton investigates Burg's cry and finds a massive den with Burg's body as well as several decomposing corpses, including Tara's.
As they bury the bodies, the Sasquatch watches them. Marla steals Huxley but a Sasquatch attacks and kills her. The others find her brutalized body and Harlan retrieves Huxley. Clayton and the others advice Harlan to leave Huxley behind. They suspect the Sasquatch knows the machine carries proof of its existence, which it does not want. Unwilling to leave Huxley, Harlan splits from the others. He is knocked unconscious by the Sasquatch and awakens next to the grave of its mate, which was killed by the plane. Confronted by the Sasquatch, Harlan shoots and destroys the machine, at which point the Sasquatch leaves him alone.
A title card explains that, upon returning to society, Clayton, Nikki, and Harlan all denied Plazz’s claims of a Sasquatch encounter.
