Half & Half focusses twenty-something half-sisters Mona and Dee Dee, who had only one thing in common when they met -- their father. Now that they have grown closer as true sisters, Mona and Dee Dee realize they share more similarities than they first thought and continue to support and comfort each other when it comes to relationships, career choices and how to handle their mothers.
Mona, a record company executive, was raised by her single mother, Phyllis, to be an independent woman who does things in her own free-spirited and sometimes sardonic style. On the heels of getting a raise for her successful talent search at Delicious Records, Mona must now try to find a balance between work, family and her search for the perfect man.
By contrast, younger sister Dee Dee, who grew up privileged in a two-parent home, continues to search for her own identity out of the shadow of her overbearing mother, Big Dee Dee. Recently graduated from law school, Dee Dee must use her newfound independence to secure the job of her dreams.
Meanwhile Spencer, Mona's best friend and colleague, is always around to help her figure out her work and relationship problems, while office assistant Adam continues to spice things up in the record company with his humorous gossip.
After deciding to take charge of her life, Mona decides to date both Chase and Lorenzo, who both agree, but later ask her to make a final decision.
Meanwhile, Dee Dee starts to date a health fanatic, but when Brett tells her the relationship won't work, she sets out to prove him wrong.
