Megan Smith, a recent graduate from Yale University unable to find success in the journalism field, accepts a job offer from Laurel Limoges - tutoring her two snobby, stuck-up billionaire twin granddaughters with the hopes of getting them into Duke University.

Megan is ecstatic to be attending a gala event of the rich and famous, where Laurel introduces her to several influential individuals. However, the event turns sour when Megan gets into a heated argument with her sister Lily, Rose spots her ex-boyfriend with another girl, and Megan has to rescue both Rose and Sage after the two get caught driving without a license.

Megan is shocked when she finds an adult DVD in Rose's bookbag, but even more shocked when Rose reveals that she is not a virgin and is planning on having sex with her current boyfriend. Meanwhile, Sage invites Lily out to a restaurant to dig up dirt on Megan and the two end up drinking together, something that infuriates Megan. Finally, Megan is worried when she thinks that Jacob might be losing interest in her.

Megan becomes more neurotic and uncomfortable when her eccentric and estranged mother Shelby, whom she hasn't seen in 16 years, suddenly shows up to visit Arthur. Megan instead confides in Charlie about her problems, which makes Will feel left out and a little jealous over Megan's friendliness with Charlie. Megan also learns that Lily has eloped with her punk boyfriend, which makes Megan feel that she's losing control even more. Meanwhile, Rose asks Marco to help set up Sage with the sous chief Louis, while Sage makes a bet with Rami the doorman to try to set up Rose with her old boyfriend Zack.

Megan seeks to aid her sister, and in so doing learns why Lily is in jail. Will offers to bail Lily out, but both Arthur and Megan refuse saying that Lily should learn a lesson by staying in jail for her long history of making the same dumb mistakes and getting involved with the wrong people. Shelby secretly meets with Will behind Megan's back to ask for his assistance, and he agrees to help... only to find out later what Shelby's real reason is. Meanwhioe, Rose helps Sage pick out a lavish gift for Luis to further get his attention, but neither sister foresees his reaction, while at the same time, Rose finds a love poem and assumes that her nebish classmate Zack wrote it for her.

While Marco and Keith plan for their upcoming commitment wedding, Rose and Sage's sisterly relationship takes a bad turn when Rose decides to ditch their annual plans for spring break and go someplace on her own, in which Sage becomes upset. Zachary too feels that Rose is maturing rather quickly, and worries about the future of their relationship. Sage has relationship problems herself when Luis tells her that he does not believe in gay marriages and refuses to attend Marco and Keith's ceremony. Elsewhere, Will and Megan have a fight over their creative differences over Will's job and Megan's mental ability to be independent. Also, Megan finally finishes her biography about Laurel who approves it for publishing.
