This exciting, if improbable, action adventure, with some devastatingly effective 'twister' sequences, follows the efforts of two rival groups of hurricane hunters to race to the root of a tornado and, by launching a scientific equipment pack into its eye, record valuable data concerning its structure. Stars Bill Paxton and Helen Hunt do all their own stuntwork, but acting honours go to Jami Gertz as the 'other woman' who comes between them.
