See firsthand the numerous changes that have led to dramatic decline of the lion population, and what needs to be done in order to ensure their survival. Live through some of the most extreme cat sequences ever captured on film.

Beyond the blood and gore lies a stark reality: Big cats kill to live and live to kill.
