Set in the near future where global warming has led to ever more ferocious hurricanes, this exciting, factually-based drama follows a team of scientists as they embark on a project to investigate ways of diverting and weakening storms. They are given clearance to fly into a small hurricane and seed it with silver iodide - a technique first developed in the USA in 1960's in a government-funded project called Stormfury. However, a dreadful accident occurs just after the seeding takes place.

The team have inadvertently created a superstorm which is now heading for New York. Being the world's largest financial centre and home to over 8m people, there is no realistic possibility that they can evacuate the city in time. The team must decide if they dare intervene again, seed the storm to try to weaken it or nudge it off course.
