They really are captivating, the most magnificent creatures you have ever seen. Mythical, the kind that have inspired legends around African campfires for generations. And they're so rare that the only ones you're ever likely to see are in a zoo, or in this story. This is the story of Mara and her precious cubs, four of the few remaining white lions on earth. Like Mara, all the survivors are in captivity. There are no white lions in the wild , none at all. But that's about to change with a rescue mission on an epic scale, a race against time across South Africa. It's a grand adventure, taking Mara and her family back home.
