"Battlestar Galactica"'s Sebastian Spence stars as the deputy mayor whose wife, meteorologist Nicole de Boer, sees a rise in wind activity as the precursor of a spate of killer tornadoes triggered by global warming. When an enormous jet stream vortex opens up over Manhattan, they have 24 hours to save the city that never sleeps from total annihilation.
