Synopsis
A bison calf struggles to survive on the North American Great Plains during its first year. As temperatures drop to 40 degrees below zero, wolves hunt in packs of 25, preying on the weak. Mothers risk their lives to protect their young while searching for food. When spring arrives, intense thunderstorms and floods transform the environment. Climate change worsens these conditions, making survival increasingly difficult for the herd as they adapt to a rapidly changing world.
