Season 1 of American television series 90210 aired on the CW television network.


Much like the original series, Beverly Hills, 90210, 90210 follows the move of a family (parents Debbie and Harry Wilson, their daughter Annie and adopted son Dixon). Harry is actually from Beverly Hills and comes back both to look after his mother Tabitha and to work as the principal at West Beverly Hills High School. All of them struggle to adjust to their new lives: Annie has a hard time balancing romances, (starting with rich kid, Ty), friendships as well as popularity and identity; Dixon has issues with his adoption and African-American heritage; Harry and Debbie struggle with the revelation that Harry has a son with Tracy Clark, his former high school sweetheart.

Tracy Clark has a daughter of her own, Naomi Clark, who dates jock Ethan Ward, with whom she soon breaks up with. Ethan gets back together with Annie, whom he had a fling with several years prior. The half-sisters (Naomi and Annie) alternate between friends and enemies in a love triangle. Their fued eventually pushes Naomi out of the "in crowd." Their mothers find themselves in a love triangle as well, after Tracy's marriage to Charles Clark implodes.

Naomi's best friend is fallen starlet Adrianna Tate-Duncan; she battles a drug addiction during the 1st season. When Harry decides to clean up the school  with the help of an under-cover cop, Kimberly MacIntyre, Adrianna finds herself caught in the middle of the investigation. Adrianna lands in rehab where she begins a relationship with Navid Shirazi, head of the school's paper and Dixon's best friend. At first she only stays to "repay" him, but they start to genuinely care about each other. Adrianna later discovers she is pregnant as a result of her promiscuity while she was addicted. After telling Navid of her pregnancy, he breaks up with her. She and Navid get back together when he realizes that, even though she is a mess, he can't get over her. They get engaged.

Another featured character is Erin Silver, Kelly Taylor's half sister and Naomi's former best friend, until Silver's father's affair is revealed. She quickly befriends Annie and starts dating Dixon, who is somewhat taken aback by her not-so-90210 lifestyle, as she is a virgin whom doesn't care about popularity. In a multi-episode arc that culminated in a very special episode, it is revealed that Silver has Bipolar Disorder. Kelly Taylor is a guidance counselor at West Beverly and has a son named Sammy. She briefly dates Ryan before leaving to work on her relationship with former boyfriend and father of Sammy, Dylan McKay. This briefly causes friction with Brenda Walsh as both struggle with their lingering feelings towards Dylan. When Kelly returns, she not only discovers Ryan's relationship with student/cop Kimberly but also that he slept with Brenda, re-creating the rift between the two friends. Following Brenda's discovery that she cannot have children, however, the women are drawn together in an accord once again.
