Tia starts working on the very first movie she's ever filmed without Tamera, and to top it off, it's a musical--which bothers Tamera because she's the sister with a singing and dancing background. Tamera struggles to grasp why she wasn't cast for the part instead of Tia--but also packs her time with other activities. While Tia is out of state filming, Tamera flies back up to Napa to help her in-laws with a wine festival.
