Tara Knowles (a researcher for Bio-Comp) and a small crew are flying over the Canadian wilderness when their plane malfunctions. They survive the crash but encounter a monster that seemingly kills them all. Weeks pass and with official rescue missions called off, Tara’s father, Harlan Knowles, puts together his own crew: his computer engineer Plazz, insurance rep. Marla Lawson, famous survivalist Winston Burg, forensic investigator Nikki Adams, and local mountain man Clayton Tyne. After arriving in the suspected crash zone, they hear loud roars in the forest. On their first night, Marla is attacked in her tent by what Clayton determines was a grizzly bear. The next day, they come across the grizzly and discover it was already mortally wounded, its neck broken with a nearby boulder.
