George embarks on his annual pilgrimage to the "Tornado Alley" area of the central U.S. to guide groups of people who want to witness the brute force of tornadoes in action. Along the way he faces giant hailstones, dust storms and quirky American roadside attractions.

Enlisting the help of fellow storm chaser R.J. Evans, George heads to Arizona to photograph spectacular lightning storms triggered by the desert monsoon season. R.J. however is known as "America's noisiest athiest" for his free-thought radio show... It seems that the gods are intent on striking them down with thunderbolts from the heavens.

In this episode, George explores the deadly Nyiragongo volcano in the Congo jungle but the lava lake dwelling inside it's crater may be the least of his worries as he has to negotiate through armed conflict, a family of gorillas, severe weather and an 11,000 foot hike up the side of the volcano.

Following in the footsteps of the Klondike goldrush, George heads north to the Yukon Territory and Alaska, but it's not gold he's seeking. It's the intense summer wildfires that often plague the area during their 24 hours of daylight. He travels by train, bike, plane and whitewater raft to reach the fires but Mother Nature has other plans for him and doesn't make things easy.

Hurricanes are the largest storms on Earth and George has been through many of them. This year he starts off by getting prepared in a wind tunnel, then he and his chase partner Mark Robinson head to Newfoundland for more wild weather action. Then, it's off to another encounter where the wild wind fans a raging inferno.
