90210是洛杉矶比弗利山的邮政编码。去年Wilson一家因Harry的工作问题，搬去了这个好莱坞明星和富豪名流首选的居住区。在这里，Anne和Dixon遇到了前男友Ethan和他的女友Naomi，叛逆的女孩Silver，有药瘾的Adrianna和校园电视台的Navid...慢慢的，他们发现这里的人际关系远比堪萨斯复杂的多。。。

It was reported that in season 2, Dixon and Silver"s relationship will suffer due to two new characters, Sasha, an African-American woman who pursues Dixon, and Teddy, a tennis champ who pursues Silver and later Adrianna.

Silver will reconnect with old friends Adrianna and Naomi.

The fashion of the show will also change, being more incline to Gossip Girl "s, where the outfits are chic and trendy.
