An unprecedented series of violent tornadoes is sweeping across Oklahoma. Tornado chasers, headed by Dr. Jo Harding, attempt to release a groundbreaking device that will allow them to track them and create a more advanced warning system. They are joined by Jo's soon to be ex-husband Bill, a former tornado chaser himself, and his girlfriend Melissa.
