Dallas bride Brandi lives in the shadow of her older, more elegant, beauty queen sister, the reigning Mrs. Texas. Brandi’s sister is on hand to steal the spotlight and to shine a light on some of Brandi’s more outrageous wedding day demands. There’s the matter of a wildly inappropriate groom’s cake, a wedding day booty shake, and a wine tasting which proves that Brandi is most certainly not her sister’s protégé. Meanwhile, Dawn’s wedding day dreams turn into her worst nightmare when a family emergency threatens to derail her entire wedding.
