Sobreviure o morir!

Courage is a strong, shaggy wolf, leader of a small pack that lived now more than 20,000 years ago, in the last ice age that Earth suffered. We are at the end of 4,000 years of total glaciation and everything is still covered in snow and ice. To survive is a feat within the reach of very few. But the days pass and the forces of the pack and its leader, Courage, begin to falter and hope disappears. When all seems lost, one night they discover what looks like a star that has fallen from the sky. Some very strange beings, hairless, who walk only on their hind legs, have brought the fire of the stars to the valley. Those "rises" may be their last hope... But what will be the price to pay?
