"It's Christmastime and Blair and Serena are best friends again and up to their old tricks- partying hard and breaking hearts from Park Avenue to the Caribbean. Blair's mom and Cyrus are having their honeymoon in St. Barts. And when school lets out for the holidays, Blair, Serena, Aaron, and company head down there to blow off steam after their midterm exams. In between Pina Coladas and topless sunbathing, Blair flirts with Aaron's handsome drummer friend and plots out her Yale essay which is inspired of course by her idol, Audrey Hepburn. Everyone jets back to NYC for Serena's New Year's party, during which the love triangle between Nate, Blair, and Jenny heats up and Serena may or may not be discovered to be the secret fling of the hottest recording artist in the music business."
