Twister

Two teams of scientists chase storms in an effort to study the behavior of tornadoes. Both compete to be the first to analyze these peculiar weather phenomena from inside a tornado. Their goal is to study in depth the largest storm to hit Oklahoma in half a century. One of the teams includes Jo Harding, a woman who, with limited resources and on the verge of divorce, must ask for help from her still-husband Bill. He gives it to her, but shows up accompanied by his new lover, Melissa. The other team, which has better equipment, is led by Dr. Miller..
