To the amusement of their adult children and friends, long divorced couple Don and Ellie Griffin (De Niro and Keaton) are once again forced to play the happy couple for the sake of their adopted son's wedding after his ultra conservative biological mother unexpectedly decides to fly halfway across the world to attend. With all of the wedding guests looking on, the Griffins are hilariously forced to confront their past, present and future - and hopefully avoid killing each other in the process. /When Sophie (Amanda Seyfried), a young American, travels to Verona, Italy-the romantic city where Romeo first met Juliet-she meets a group of volunteers who respond to letters written to Juliet seeking romantic advice. Sophie finds and answers a letter that has been lost for 50 years, and is stunned when its author Claire (Vanessa Redgrave) arrives in Italy with her handsome but overprotective grandson (Christopher Egan) to find the fiance she left decades before. Fascinated by Claire's quest, Sophie joins them on an adventure through the beautiful hills of Tuscany searching for Claire's long lost Lorenzo. The journey will change their lives forever, as they discover it's never too late to find true love.
