Tornado Alley documents two unprecedented missions seeking to encounter one of Earth’s most awe-inspiring events—the birth of a tornado. Filmmaker Sean Casey’s personal quest to capture the birth of a tornado with a 70mm camera takes viewers on a breathtaking journey into the heart of the storm. A team of equally driven scientists, the VORTEX2 researchers, experience the relentless strength of nature’s elemental forces as they literally surround tornadoes and the supercell storms that form them, gathering the most comprehensive severe weather data ever collected.
