Welcome to New York City's Upper East Side, where the girls are dazzling, the guys are gorgeous, and the summer heat is the perfect excuse to throw a fabulous roof-deck pool party. As if we need a reason! It's our last summer together before heading off to college, and things are sizzling -- no, it's not just the weather. Despite that steamy kiss on graduation night, Blair, Serena, and Nate have gone their separate ways...though not for long.
Blair is off to London with her English Lord boyfriend, Serena's about to become a movie star -- as if she wasn't a star already! -- and Nate's rolling up his well-worn khakis and heading to the Hamptons. Back in New York, Dan and Vanessa are rekindling their love. Fiery! Watch out, this summer is going to be hotter than ever.
Serena is living it up in the original apartment Breakfast at Tiffany's was filmed, while Blair is in London with Lord Marcus. Nate, meanwhile, is fixing up his coach's house as part of his summer work deal, but will he stick to it?
Whilst in London, Blair gets up to her usual tricks, she buys - among other things - a £10,000 wedding dress, which ends up at a staggering $18,000 when she brings it home. But things are far from rosy with Marcus and when a "cousin" turns up with her touchy-feely ways, can Blair hold her own or will she give up and go home?
Serena is finding acting harder than she expected; she has a hot new co-star, Thaddeus, who she flirts with and expects a reaction, but he just rejects her time and time again. She finds it almost impossible to learn lines, doesn't get on well with her boss, and to top it all off, there is a cute guy living below her who can't believe his luck.
Vanessa starts filming for Breakfast at Fred's while crashing at Dan's; Dan is hanging out with a yoga-loving, bookstore-visiting girl, but will he two-time on V, his one true love? well as we learn to be loved we also learn to hate, but what is the most powerful one....
