Kate, a meteorology student, chases a tornado through her native Oklahoma with her boyfriend and a few friends for her class project: she comes up with the idea of spraying a mixture inside the tornado that could theoretically destroy it. Nature wins - three, including the boyfriend, die, and only Javi is left alive, except for Kate.
Five years later, he finds her in New York at her office job and convinces her to go back to the field for a week. It's just tornado season in Oklahoma, and Javi has a big team and serious funding. The first thing they encounter on site is a group of reckless YouTubers led by cowboy meteorologist Tyler.
