In the summer of 1969 Jo Harding is rushed to her family’s storm shelter when the television announces a severe weather alert. As her father holds down the shelter door, a tornado sweeps over the top, ripping the door from its hinges and carries him to his death. From that day on, Jo vowed to hunt as many tornadoes as she could, and works on a team of professional storm chasers.

Bill Harding is a retired storm chaser who is now becoming a weatherman. He is also Jo’s husband. He seeks out his ex-teammates with his girlfriend Melissa, to have Jo sign the pending divorce papers. The team is analyzing a storm when Bill arrives, and Jo stalls for the papers. She is in denial about the separation and isn’t ready for the marriage to end. But with Bill’s girlfriend close by, changing his mind will be quite the challenge.

The team is testing out a tornado-analyzing device that was initially Bill’s idea. The device is called “Dorothy,” and Jo wants Bill out on the field for her first use. If Dorothy is a success, a more accurate warning system can be developed.

The team gets wind that there is a tornado approaching nearby. Jo and Bill go ahead of the group to see the tornado up close, with Jo’s truck being lifted off the ground by its force. Battling for their safety, they place Dorothy directly in the line of fire.

The storm chasers sit down for a hearty meal at Aunt Meg’s. While swapping stories from years of adventures the crew chows down on juicy steak and eggs. Don’t torture yourself by watching, cook some for yourself!
