Yellowstone: Battle for Life (Blu-ray)

Take the most astounding visual tour of one of the world's most spectacular wilderness areas. An American treasure that's larger than some states, Yellowstone's natural beauty and majesty include some of the richest wildlife beyond the plains of Africa. From hungry wolves descending on a buffalo to a mother grizzly tending to her cubs or elk and moose fighting for dominance, this vivid, wonderfully shot film reveals amazing tales your entire family will cherish.

Winter: The Wolf's Story - Yellowstone in the depths of a bitter winter: beautiful and full of peril. Survival is everything. The Druid Peak wolves are expert hunters in the snow - and confident enough to take down fully-grown buffalo. But as spring draws out, hungry bears begin to emerge from hibernation, and violent fights with them and with the rival wolfpacks put the Druid Peak wolves' future in jeopardy. Will any of them even survive into the summer?

Spring: The Grizzly Bear's Story - As a grizzly bear family emerges from their den at Snake River, the mother finds an abundance of food for her new cubs. She has to fight to defend her prey against the newly-dominant wolves, bald eagles and the local coyotes. It's a time of great activity - and the cubs' curiosity constantly puts them in danger...

Summer: The Great Herd's Story - As summer turns into vivid autumn, the mood of the landscape changes again. There's a spectacular gathering of herds across the plains: testosterone fuelled elk, buffalo and moose in their thousands start their annual rut, calling so loudly they can be heard three miles away. Belligerent, unpredictable and very dangerous, the bulls can fight until injury or even death stops them. The Druid Peak wolves and our Snake River grizzly family are ready to take the spoils of weakened animals that will feed them into the approaching winter, before it takes its icy grip once again?
