The Upper East Side is thrown for a loop when Gossip Girl reports that Serena van der Woodsen, Manhattan's most notorious party girl, has arrived back in town after a mysterious absence where no one knows where she was or why she left. Not even Serena's closest friend, Blair Waldorf, knew her whereabouts and is shocked to learn Serena has returned. However, their once close friendship is complicated upon Serena's return, strained now that Serena is the center of attention and Blair has been cast from the limelight, and the revelation that Serena had a fling with Blair's boyfriend Nate Archibald.
Also ruling the Upper East Side is Chuck Bass, son of the wealthy and powerful Bart Bass and a friend of Nate's since childhood. Chuck leads a reckless life, which often leads Nate down a similar path of darkness and destruction.

However, Dan and Serena's worlds collide following a chance meeting where Dan quickly finds himself dating the girl of his dreams. The closer they become, the more Dan learns about the real Serena and how different she is from the world in which she lives.
With all of the ever-changing drama in the lives of the teenagers and adults alike, the ever-present Gossip Girl is always around to keep up on the complex and intriguing world.
