A lioness was followed in her fight for survival over the course of two years for new documentary The Last Lions.

Narrated by Jeremy Irons, the film was made by husband and wife team Dereck and Beverly Joubert.

The Jouberts say the film is an effort to draw attention to the dramatic decrease in the world's lion population.
