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.

Dee Dee's life changes direction when she gets an unexpected career opportunity.

Dee Dee must resolve her differences with a competitive co-worker, Brett Mahoney (Joey Lawrence), in order for them to win over a new client.

Phyllis tries to set Mona up with handsome firefighter Glen (Coby Bell), but he winds up falling for Phyllis.

The sisters are in a bidding war when Dee Dee's first client decides to give up baseball for a musical career.
