Romantic ensemble comedy following the lives and loves of several New York singles and couples on New Year's Eve. Harry Buckingham (Robert De Niro), a dying man confined to his hospital bed, seems unlikely to have a happy New Year. Perhaps Ingrid (Michelle Pfeiffer) will have more fun as she decides to use the last few hours of the year to try and complete her unfulfilled resolutions. Elsewhere, Sam (Josh Duhamel) is desperately trying to make it to New York to meet up with a woman he met last New Year's Eve, while Tess (Jessica Biel) is due to give birth. The star-studded cast also includes Sarah Jessica Parker, Ashton Kutcher, Katherine Heigl, Zac Efron and Hilary Swank.
