As the drought drags on with the sun continuing to blaze down from a cloudless sky and harvest time gets closer, Jeremy Clarkson and his motley crew have a fearsome list of jobs to complete.

Within the earth, right beneath our feet, are strange and sometimes deadly secrets. Earthquakes, tsunamis, and volcanic eruptions are just some of the phenomena that are driven by hidden forces deep inside our planet. With the latest sensors and surface scans, a virtual X-Ray of the earth can be generated for study.
In the first episode, we will explore how a vast fault 80 miles off the Pacific Northwest coast. With pressure building for over 300 years, a slip would result in a megaquake and tsunami that will devastate the region threatening 15 million people.

A mammoth Tsunami strikes the eastern seaboard. It would be a disaster of epic proportions. Some scientists believe this catastrophe could happen one day, but how? This episode shows the Atlantic island of La Palma has collapsed several times in mega-landslides. Another could trigger a tsunami with enough power to cross the Atlantic Ocean and decimate the US East Coast.

Beneath Yellowstone National Park, lies the biggest volcano on Earth. An eruption in the past was so big it plunged the earth into a volcanic winter that lasted years. A super-eruption would be more than millions of Hiroshima bombs going off all at once. It would be even worse than an asteroid impact: Entire cities lost beneath ash, people and animals crushed alive, power networks destroyed, sun dimmed across the globe, harvests failed, widespread famine. Could this nightmare really happen? We will use the latest scientific data to uncover the danger beneath us, as we see our planet like never before.

The Sun is a endless churning cauldron of nuclear reactions and our planet is at its mercy. Revealing its inner workings was once mission impossible, but not any more. We've recruited a fleet of spacecraft that monitor the Sun 24 hours a day, under close surveillance. We just might have what it takes to defend our planet.

They're the cooling corpses of stars like our sun, but new research proves white dwarfs are one of the driving forces of our universe. And they can tell us literally about the nature of the cosmos itself. Have scientists finally discovered how these small stars could be such massive galactic players?
