The complete, explosive and action-packed first two seasons.

Every spring, changing weather patterns create a recipe for catastrophe as air masses collide into each other with devastating force, producing deadly twisters. And every spring, a collection of scientists, enthusiasts and eccentrics brace themselves for another series of storm chasing.

They hope to spot one of mother-nature's deadliest and violent creations. But for this team, seeing a tornado is not enough. Their goal is to achieve the unthinkable and actually go inside the tornado.

Series 1 of Storm Chasers follows research meteorologist Dr. Josh Wurman, who has teamed up with extreme filmmaker Sean Casey. Filming from the turret of his self-designed and built Tornado Intercept Vehicle (TIV), Sean puts his life on the line as he endeavours to get the most dramatic tornado footage ever shot.

As Series 2 of Storm Chasers gets underway the newest chaser, Reed Timmer, pits his light and loose style of chasing against the heavyweight, methodical approach of Josh Wurman and his crew. Meanwhile, the eight-tonne, 10-wheeled TIV2 makes its debut as Sean Casey continues his quest for the ultimate IMAX tornado footage.
