Hannah (Michelle Monaghan) and Tom (Patrick Dempsey) are just friends. Just two attractive folks who make each other laugh, know everything about one another, and prefer each other's company to any one else, but they could never be romantically entangled, right? Wrong! When Hannah gets engaged to another man, Tom secretly tries to woo her, attempting everything he can think of to prove that they're a match. Finally, he rides on horseback to her picturesque Scotland wedding, flies through the doors, and breaks up the ceremony.
