After Susan and Michelle return in despair from their time-travel journey back to 1999, Michelle resigns herself to a life of loneliness and Susan accepts the fact that she's lost James forever. James, a former member of the most famous band of all time, and Susan, the woman who's loved him for over fifty years, were to be married in a double ceremony on Christmas Day, 1999 with Thomas, James's son, and Michelle, Susan's daughter. It was not meant to be, however, when a gold-digging ex-courtesan, determined to have James for her own, exposes Susan as already being married. It's now August 2016 when Thomas is preparing for a move from London to Los Angeles and discovers the mobile phone Susan left behind. The “mysterious object,” as he thought of it seventeen years earlier, is at the bottom of a box in his closet that he'd packed up with Michelle's things shortly after she and her mother vanished. When Brett, Thomas's friend who works for Apple, examines the phone, telling him it's an iPhone6 and there's no way he could have had it for seventeen years, both men are puzzled. Will the mystery of the phone be solved and will it lead Thomas back to Michelle? And, if Michelle and Thomas are reunited, is it possible that Susan and James will once again find themselves in each other's arms? After all, we know from Susan's previous forays into the past that history could not be changed, but what about the future? Will there finally be a “Happily Ever After” for James and Susan?
