Half-sisters Mona and Dee Dee are virtual strangers who have grown up separately and suddenly become neighbors in the same San Francisco apartment building. Mona is a budding music executive raised by her single mother to be free-spirited and independent. By contrast, younger Dee Dee is a privileged honor-roll collegian who grew up in a two-parent home but seeks her identity out of the shadow of her overbearing mother.

When Mona finds out that Dee Dee has reunited with her ex-boyfriend (Yancey Arias), she is disappointed that Dee Dee did not trust her enough to tell her.

When Dee Dee turns down Mona's request for a favor, Mona regrets telling her not to let people take advantage of her.

Mona and Dee Dee arrange a blind date for Spencer.

Dee Dee wonders why her boyfriend doesn't seem interested in becoming intimate; Mona takes up smoking again.
