Blair is envied by her adversaries because she is thought to have the perfect life, not just because of her gorgeous boyfriend, Nate Archibald, but because she's also planning on getting into her dream college,Yale. With everyone worried about college(or procrastinating on worrying, which everyone seems to be doing), and senior year dragging along, her seemingly perfect life is interrupted by her ex-best friend, the beautiful Serena van der Woodsen, coming back into town after getting kicked out of boarding school.
Serena comes back into her life, and into the eyes of Blair's boy friend. When everything Blair knows starts to fall apart, everyone will realize that her life is far from perfect. Will life in the the Upper East Side redeem itself of what it's really supposed to be? Or will the false facade reveal that the rich have the same problems as the not so rich (Jenny and Dan Humphrey), if not more. And just maybe Jenny and Dan are all the more happy with their simple, not so expectant lives.
