Life is sweet for Nikki Sands... She's toasting her new job at Malveaux Estate in Napa Valley and balancing a love triangle with a neighboring winemaker and her boss, vineyard owner Derek Malveaux-the catch of the county. And tonight, Nikki will be on the arm of Napa's golden boy at a Sonoma mansion for the wedding of the decade. Nikki's friend Isabel agreed to cater the wedding-before she learned that the groom was her cheating lover. After the ceremony, Isabel asks Nikki to bring the obnoxious bride another glass of wine. However, the bride won't be drinking that glass of wine or any wine ever again asNikki finds the new wife sprawled on the floor-murdered. Since the dearly departed made enemies easily, there's a bushel of suspects-many of them close to Nikki. Now, it's up to her to get to the bottom of what may have been a killer bottle of wine.
