Meanwhile, Brenda develops a crush on her math teacher which affects her even more when she's asked to baby-sit for his two wild children for the evening in which Brenda asks Kelly and Donna to tag along with her.

Brenda botches her third try to get her drivers license, but she goes out anyway to rescue Kelly from a bad date, and in the process, loses Brandon's car. Meanwhile, Brandon decides to try out for the school's basketball team where he suspects that some students are brought into the school from out of district for the sole purpose of winning games and he asks Andrea to look into it.

Close to failing history, Brandon (at Steve's persuasion) resorts to cheating from a copied term paper, which leads him to debate honesty vs. an unfair teacher, as well as his friendship with Andrea when she catches him cheating. Meanwhile, Brenda and Kelly both have the hots for Dylan, so Brenda tries dying her hair after he states his preference for blonds. But she comes out with ugly orange streaks.

Brenda becomes fascinated by Kelly's hip mother Jackie. But Brenda is unaware about Mrs. Taylor's alcoholism and drug use which makes life hard for Kelly. It's not until at a West Beverly High Mother/Daughter beauty pageant that Brenda finds the truth which gives her a renewed appreciation for her own mother. Andrea blossoms at the pageant while writing an article about it. Also, Jim becomes hooked on playing his new electronic keyboard in singing old songs.

Brenda finds herself in a crisis when she gets to know an unseen student date-rape victim from Andrea's volunteer help line. Meanwhile, Brandon gets tempted by an older woman, named Nina, who specializes in health massage solutions.

When Brenda finds herself falling in love with Dylan, it results in Brandon's wariness and Jim strongly opposed to it due to Dylan's lifestyle and his father who gets indicted for corporate financial fraud. Meanwhile, Steve meets a woman who will be speaking at an AIDS seminar at school which leads everyone into discussing condoms.

Cindy and Jim get an interesting proposition from an eccentric, swinging couple while spending a weekend together in Palm Springs.

Brandon learns some pitfalls of parenthood when he starts dating Melissa, a senior girl who has a six-month-old baby. Meanwhile, Brenda and Kelly win free skydiving lessons on a radio call-in show. After a few days of skydiving practice, they decide to set aside their fears of falling and take the plunge, literally.

But the evening turns sour when Kelly's venomous girlfriend, Amanda Pacer, joins the party and starts a game which brings out secrets that threaten the friendships between all of them. Meanwhile, Brandon and Steve go out together for a night of cruising and club hopping in which they end up getting duped by two girls who steal Steve's car.

The Walshes allow a young Latino girl named Karla Montez, (their maid Anna's niece) to use their address so she can attend West Beverly High School. Brandon becomes intrigued with Karla, but he suspects that she's hiding something due to her wariness and a strange man following her around. Later, when Jim arranges a party for one of his clients, Brandon causes a scene when he finds Karla at the party serving drinks and thinks she's being used as cheap labor.

During Presidents' Weekend, the gang goes to Palm Springs, where Dylan and Brenda plan to meet at a hotel for some time alone.

Meanwhile, David, wanting to fit in with the gang, ditches Scott and their trip to Magic Mountain to take Steve, Kelly and Donna to his grandparents' house, which is supposed to be empty. And Brandon stays home to help Nat at the Peach Pit, and discovers a secret that an apparently sarcastic boy named Curtis has been hiding.

A right look at the right time and in the right place in a local park gets Brandon a role on a TV series and he gets to work with the teenage lead actress Lydia Leeds, while becoming an instant celebrity at school.
