In the Atlantic Ocean, hurricane Helena is gathering strength, becoming the most powerful storm in recorded history. As Helena bears down on Bermuda, Donovan Nash, along with other members of the scientific research organization Eco-Watch, are called to fly in and extract key government people who have been studying Helena. For Donovan Nash, the routine mission turns deadly when an attempt is made on the life of the lead scientist. A woman from the past, Dr. Lauren McKenna, is suddenly thrust back into his life. With 300 mph winds and waves over 90 feet, Helena marches relentlessly for the vulnerable east coast of the United States. In a bold attempt to diffuse the power of the hurricane, Eco-Watch is called upon to conduct a final flight above the massive fury, where the jet suffers a catastrophic engine failure. Now the only option is to maneuver the crippled airplane into the calm of Helena's eye.
