Though on the brink of divorce, husband-and-wife meteorologists Bill Paxton and Helen Hunt work together to test a new storm-warning system, braving some of the most destructive tornados in movie history as they try to stay a step ahead of rival storm chaser Cary Elwes. Oscar-nominated special effects send cows flying through the air and buildings tumbling to the ground in this blockbuster helmed by action specialist Jan de Bont and co-written by Michael Crichton.
