Between licking wounds and hunting, six male lion cubs were born in the primitive world. Using each other's backs as the foundation stone, wandering was tempered into loyalty, and violence evolved into order. They measured the grasslands with their fangs, demarcated the borders with their roars, and established a prehistoric empire about protection, power and blood inheritance on the land watered by blood. This is not only an epic of nature, but also a profound fable of how life gives birth to kingdom, responsibility and love from the wilderness.
