Teams of expert storm chasers and certified weather spotters risk it all to venture into America's Tornado Alley. They self-shoot their encounters with nature at its most extreme, warn people in harm's way, and help save lives when disaster strikes.

In the premiere episode, veteran chasers and a new generation of storm spotters and weather streamers compete for position during one of the season's most volatile tornado outbreaks. As a photogenic twister approaches the small town of Gary, South Dakota, each chaser angles to get ahead of the storm. But when extreme meteorologist Reed Timmer arrives with his high-tech armored vehicle, called "the Dominator," an unexpected fender bender disrupts the chase. Back on course, the chasers catch up with the fast-moving twister, but as it intensifies to EF-3 strength, it takes a terrifying turn. Realizing the tornado is about to destroy a farmhouse, chasers Brandon Copic and Will Vollman shift from storm chasers to first responders, launching a search-and-rescue mission inside the wreckage with the tornado still in sight.
Six teams of chasers pursue a violent tornado outbreak in North Dakota. But as day turns to night, the storm unleashes the first EF5 tornado in over a decade. As the mile-wide monster levels homes and farms, chasers race to rescue people and pets.
