Academy Award winner Helen Hunt stars as the leader of a rag-tag band of tornado chasers on a perilous quest to test a new sensor device. Bill Paxton plays her fellow scientist and estranged husband who unwittingly joins her crew on this meteorologically active day. Perhaps they can make amends and salvage their marriage, but only if they can survive--the twisters. State-of-the-art special effects stir up this gripping, smash-hit action-adventure directed by the master of action himself--Jan de Bont.
