A great drought has enveloped the lions' land, a plague known as the Endless Summer. As the animals leave and the lions refuse to follow, they face starvation on the plains. Their only hope is for the Pantheraseer to lead them to the promised land, where green grasses flourish and prey abound. But will the lions be able to accept the Pantheraseer as their leader? In the absence of the legend, the cats have grown hostile. Their desperation for food and water has made them prejudiced against members of their own kind. They trust no one. Before they can ever hope to be saved by Panthera, they must learn to accept each other and the Pantheraseer, and he must learn as well what it means to lead.
