The fascinating landscape formations of Iceland in the North Atlantic bear witness to the beauty and primal power of nature. They were created through the interaction of powerful volcanic, geological and biological processes that have been changing the face of the earth for billions of years. This is what the Earth might have looked like four billion years ago. Iceland is the realm of ice and fire. Nowhere else is there such a high density of volcanoes. The landscapes, which are continually reshaped by eruptions, make the island a natural laboratory full of clues about the formation and development of the earth. The documentary follows a group of scientists through the most active areas of Iceland, along a mountain range that has emerged from the ocean. On the slopes of the volcanoes, in the fog of the fumaroles and on streams and rivers, the three researchers explore how the first forms of life populated the earth's surface and in what evolutionary steps they took over the earth.

Mario and Ana, in voluntary exile from Buenos Aires, live in a remote Argentine valley with their 12-year-old son Ernesto. Mario runs a school and a wool cooperative; Ana, a doctor, heads a clinic with Nelda, a progressive nun. Into this idealistic family comes Hans, a jaded Spanish geological engineer -- surveying the land for the local patron, to see if it can be dammed for hydro-electric power, which would drive the peasants from the land into the cities.

In the Sahara desert, a sandstorm batters a deserted drilling station. A security patrolman battles through the high winds to investigate why all contact with the station has been lost. Originally built for gas exploration, and then abandoned, the site had recently been taken over by a multi-national research team intent on drilling deeper into the earth’s crust than ever before.

The Australian Aborigines (in this film anyway) believe that this is the place where the green ants go to dream, and that if their dreams are disturbed, it will bring down disaster on us all. The Aborigines' belief is not shared by a giant mining company, which wants to tear open the soil and search for uranium.

Rocks from a meteor which grow when in contact with water threaten a sleepy Southwestern desert community.

Scientists discover a giant creature under the Earth that is wrapped around the entire planet. When the creature wakes all grumpy, it causes worldwide destruction.

The irrepressible Donald Barry is twice falsely accused of murder in this typical low-budget but well-mounted Republic Western. Barry plays Jim Randall, a lawman assigned to investigate a series of gold shipment robberies. Arriving in the middle of a hold-up, Randall finds himself accused of killing the driver (Yakima Canutt). Wells Fargo agent Cal Chambers (Milton Kibbee) vouches for his innocence, however, claiming him to be a noted geologist. Along with several of the prospectors, Jim devises a plan to prove that Jud Parker (Harry Worth) is using his dummy mine as a cover for stealing ore.
