Twister (1996)

TV weatherman Bill Harding is trying to get his tornado-hunter wife, Jo, to sign divorce papers so he can marry his girlfriend Melissa. But Mother Nature, in the form of a series of intense storms sweeping across Oklahoma, has other plans. Soon the three have joined the team of stormchasers as they attempt to insert a revolutionary measuring device into the very heart of several extremely violent tornados.—Martin H. Booda
