People disappear every year out in the snow, but now something is adding to the body count. Jim (John Schneider) and his research team study the Canadian Lynx each spring. This year, he has to take his rebellious 16 year-old daughter, Emmy (Danielle Chuchran), with him. But the lynx are missing. As Jim and his team--with the help of a local ranger (Jason London)--try to find out why, something stalks them...a predator no prey can escape.
