The off-kilter, unscripted comic vision of Larry David, who plays himself in a parallel universe in which he can't seem to do anything right, and, by his standards, neither can anyone else.

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.
