Marvel at "Old Faithful" erupting, vast rolling forests, abundant wildlife, thundering waterfalls, gurgling hot springs and mud pots, and the beautiful, haunting wilderness. Over 2.2 million acres located in the northwest corner of Wyoming, the great Yellowstone National Park was founded in 1872. The superb camera work of Dale Johnson and Bob Landis captures the natural wonders that captivated the early mountain men of the 1840s: petrified forests, mountains of glass and rivers that cooked fish. Thrill to rare and dramatic wildlife action; an antelope doe chasing a coyote from her young, a grizzly pursuing an elk in a life and death chase, a coyote matching wits with an otter; northern elk migrating in deep snow and bighorn sheep in mating battles. See the Yellowstone fire of 1988, and the charred land in full bloom. Ride with a park range into the backcountry. Enjoy a stagecoach ride to a sunrise cookout. It's all here, the magic of the great Yellowstone.

Otters are so proficient at capturing the fish they live on, that they have lots of time left over for play. And they seem to play with reckless abandon, sliding down steep canyons in deep snow, swimming under the ice in Yellowstone Lake. They submerge us into the lake to find strange underwater spires only recently discovered by man. Other creatures sometimes survive bitter winter seasons by stealing fish from the otter. Actually, they're pretty good at defending themselves, and this program catches some astonishing action between them, coyotes, eagles, beaver, even an occasional grizzly bear.

At first glance, it's just like other European plains. Once the wind and rivers worked on it, today it bears the signs of human activity. The Hungarian Puszta is different nonetheless: it lives a secret life where always happens something. Big birds hustle and push each other, the traffic of the white, salty lakes competes that of major airports, antlers clash like swords, and an owl claps on all this. The most peculiar creature is the protagonist itself. The golden jackal once lived here, but it vanished for decades because of constant persecution. But this four-legged predator, defying the danger, has returned and founded a family. The new pack howls in the frosty night: "This is our land!"

A group of renowned cosmologists and astrophysicist are in search of a realistic picture of the universe. Their research and observational discoveries point in a direction diametrically opposed to the predominant Bog Bang theory - this leads to a series of sociological situations that verge on the extreme dogma controls wielded against Copernicus and Galileo in the past; only now against our protagonists of the 21st century. This is a controversial science documentary touching on the nerve of everything astronomers and cosmologist claim they know about the universe today. - Written by Meyers, Randall
