Forces of Nature (1999)

Ben has to get from New York to Savannah for his wedding to Bridget. He has everything under control until an eccentric young woman named Sarah literally falls into his life... and atmospheric conditions become decidedly unstable. Despite being detained, derailed and disrobed, panic doesn't really set in until Ben realizes that he's developing a definite attraction to the sexy and impetuous Sarah... and the feeling is decidedly mutual. It seems that man, machine and the forces of nature are conspiring to keep Ben from his vows, leaving him to wonder if this is some kind of cosmic test... and if it is, will he pass?
