Greg Johnson, Chris Chittick, and Ricky Forbes are the Tornado Hunters.

They have a plan, and it's simple. They're going to find the biggest, baddest tornadoes in North America, and head straight for them. If they can keep four wheels on the ground, they'll capture the world's best, most extreme storm imagery, and turn their passion for storm chasing into one hell of a way to make a living.

After an incredibly successful 2014 chasing season—and an encounter with twin tornadoes, the "holy grail" of storm footage—expectations are higher than ever for the guys in Canada's only full-time storm-chasing business. Their quest for one-of-a-kind footage of the world's most violent storms will take them up, down, and all across Tornado Alley, following on the heels of storms that at any moment could turn from photogenic to tragic.

Of course, not every day brings a tornado, so on their down time, they make pit-stops in Mississippi to handle snakes, learn some much-needed desert survival skills in Arizona, and take a side-trip to Florida to chase waterspouts. When the lifeblood of your business is extreme weather imagery, building and maintaining a reputation for edge-of-your-seat adventure is part of the game.

As some of the most successful storm chasers in the business, the Tornado Hunters are no strangers to extreme weather or extreme danger. But not all the perils of chasing come from Mother Nature—wedding bells, financial worries, and growing rivalries mean the team must continually deal with the pressures of real life while aiming themselves right at the 300 mile-per-hour winds of an EF5 tornado and saying "let's go."
