Airing Dec. 16 at 9/8c on USA, the movie will, for the first time, show the Hamptons during the wintertime as Evan and Paige prepare to say "I do" complete with bachelor and bachelorette parties that both somehow end up in Las Vegas. In Sin City, someone will take "a big gamble on the future" and Paige must deal with an impending snowstorm threatening to hit the Hamptons on her big day and make her wedding a little too white.

The bumpy road to the altar will also include Jill's return from Africa as well as the introduction of Hank's first love (Buffy's Emma Caulfield) in flashbacks. The flashbacks will show how his relationships with his past loves and his brother, Evan, got him to where he is today and come just as Dr. Hank (Mark Feuerstein) begins to suffer from his own medical problems.

Will Hank be able to cure his own ailment? Is Jill back in the Hamptons to stay? Will Evan and Paige actually tie the knot? Tune in for Royal Pains' special two-hour event, airing on Sunday, Dec. 16 at 9/8c on USA.
