Delicious Records is bought out; and a new boss, respected music business veteran Kai Owens, takes over the company. She is bringing many of her own associates along, so she begins conducting interviews to see which employees will get to keep their jobs. Adam, exhilarated by all of the drama, giddily celebrates each new firing by banging a gong. Mona fears that she will be the next to go because she is terrible in interviews. Despite Dee Dee's advice, she blows the interview. However, Kai respects her work so much that she promotes her to a Vice President position. This makes her Spencer's boss, and he has trouble adjusting to the situation, ignoring her orders and talking back to her. Mona worries that they will not be able to maintain their friendship. Meanwhile, Dee Dee pleads with her mother to let her make a connection with her unborn brother in some way. Big Dee Dee offers to let her name the baby.

Kai orders Mona to exercise some of her new power as a vice president by firing Adam. She feels terrible about doing this to her friend, but acknowledges that he isn't a very good receptionist and finally breaks the news to him. Adam is furious and refuses to take any of her calls. Mona later learns that Kai never wanted her to fire Adam (who constantly sucks up to her and shares all the gossip), and had him confused with someone else. Mona must track down Adam at his new job handing out sausage samples at the mall and convince him to put aside his pride and return. Meanwhile, Big Dee Dee hires an accomplished and extremely hot male nanny to care for Drew, but realizes she must let him go after she and Dee Dee spend all of their time fantasizing about the man.

Dee Dee vies with her law school rival, Stephanie Seymour, for a summer internship. Dee Dee believes that she is the more qualified candidate; but Stephanie sucks up to the man in charge, Mr. Washington. She also tries to use her sex appeal to her advantage, so Dee Dee retaliates by showing up for her final interview in a revealing outfit. She gets the job, but Mr. Washington's comments and behavior prompt her to fear that she got the job for the wrong reasons--and that her new boss might want something in return. Meanwhile, Kai develops a crush on Spencer and asks Mona to pass along this information to him. Spencer is thrilled, and decides to get involved with Kai and try to use her for career advancement. However, he panics when she starts talking about a relationship during their first date.

Mona returns from a Hawaiian vacation and clears the air with Spencer. They reaffirm their decision to just be friends. While looking through some vacation photos with her family, Mona reveals that she can now ride a horse. She is stunned to learn that Dee Dee still has the horse their father gave her as a child, Daddy's Favorite, and that she has lied for years about having not kept the horse. (The horse led to a major rift between Charles and Phyllis that separated the sisters for a decade.) Mona decides to buy her own horse, but it doesn't quite go as planned. Meanwhile, Adam helps Spencer uncover the cause of Kai's sudden unpleasant attitude toward him.

Mona must work long hours as she prepares a major presentation for Kai about her talent search idea. She begins to lose touch with her family and friends, as she misses out on Dee Dee's weekly parties and is unaware of major news like Spencer getting a new girlfriend and Phyllis and Ray deciding to live together. Mona makes an effort to better balance her personal and professional lives, with disastrous results. Meanwhile, Adam, upset that being gay is no longer the ""in"" thing, decides that he is going to be straight.

Kai reluctantly agrees to give a shot to Spencer's friend RJ Jackson, a talented and successful singer with a reputation for partying. Spencer has difficulty reining in RJ, and must resort to desperate measures to get a track recorded before the deadline. Meanwhile, Big Dee Dee decides to return to the stage after helping Adam prepare for an acting showcase.

After hiding the relationship for a month, Dee Dee reluctantly introduces Carter to her parents. They are surpisingly supportive. However, Big Dee Dee immediately goes to Mona and pleads with her to try to sabotage the relationship, as she and Charles believe that Carter is completely wrong for Dee Dee. Dee Dee is furious, and winds up surprised by Carter's reaction to the situation. Meanwhile, Kai provides Mona and Spencer with an assistant, who livens up the office but doesn't seem to do any actual work.

Mona becomes upset when Kai repeatedly refuses to give her credit for the Fast Track contest in interviews. Mona, at her family's urging, tries to seize some of the credit for herself, with disastrous results. Meanwhile, Big Dee Dee gets in touch with her agent so that she can resume her acting career. She winds up playing second fiddle to Coco in a dog food commercial.

Mona panics when a screw-up by Spencer may cost Delicious a chance to have mega-successful producers Jimmy Jam and Terry Lewis help judge a showcase with the talent search finalists. Meanwhile, Dee Dee tries to prove to Mona that she can get by without their father's assistance after she gets downsized from her new job before her first day.

Mona grows very nervous about her role in selecting the Fast Track winner, especially after Kai decides to step aside and leave the decision about whom Delicious will sign to Mona. Dee Dee urges Mona to have confidence in her abilities. After a workshop, studio session and live showcase, Mona, Jimmy Jam and Terry Lewis select the winning act.

Mona entertains overtures from the head of a rival record company, who hopes to hire her away from Delicious. She seeks her father's advice on how to handle the situation, leading to resentment from Phyllis. Meanwhile, Big Dee Dee plans a lavish 15-month ""birthday"" party for Drew in the hopes of showing up her friends.

Mona refuses to go along with Spencer's desire to sign a talentless but popular heiress to Delicious. He infuriates her by finding a way to pitch his proposal without her approval. Meanwhile, Big Dee Dee is jealous when Phyllis teaches Dee Dee a series of money-saving tips to help her adjust to her new financial standing.

Mona goes against her initial instincts and decides to attend her ten-year high school reunion, where her professional accomplishments cannot protect her from the cruel comments of a pair of former cheerleaders. She perks up after a successful classmate takes an interest in her. Meanwhile, things do not go as planned for Spencer when he meets his on-line sweetheart in person; and Adam tries to get rich by stealing company supplies and selling them on the Internet.

Mona realizes that she needs to slow down her relationship with Chase after they start spending so much time having sex that it begins to affect her job and other aspects of her life. Dee Dee plans a "legends ball" on behalf of her mother (who is depressed because of her floundering acting career), but finds that none of the invited guests want to attend. Spencer buys a gigantic new truck that soon leaves him financially strapped because he can't afford gas.

Dee Dee receives the opportunity to appear on a sports talk show, only to humiliate herself by falling flat on her face. Mona objects when Spencer and Adam constantly give in to Dalis's petty demands. She finally puts her foot down, with disastrous results.

Mona is taking her break-up with Chase out on everyone, only to realize that she's also putting her professional career in jeopardy. Dee Dee's newly signed client is married but when she suspects he's having an affair she is faced with a moral dilemma. Meanwhile, Phyllis and Big Dee Dee assume the girls are planning a big Mother's Day celebration, since neither has suggested plans to celebrate.

Mona discovers everyone is hanging out with Chase behind her back. Gus leaves town, leaving Brett in charge of the office. But when Dee Dee's colleagues tell her he is envious of her new responsibilities she tries to keep the peace in the office. Meanwhile, when Mona begins to see a therapist she realizes she has to take control of her life.
