Baroni Vineyards is opening a new sparkling-wine facility. Private investigator Nick Polo tags along to the gala with reporter Jane Tobin. Amidst the fun, Nick takes a case at the behest of Angelo Baroni. Someone is sabotaging his vineyards: a tank of chardonnay spoiled, irrigation systems dismantled, theft, and--the weekend of Nick's visit--arson. The competition in wine is fierce, so it could be a business rival, but an inside job is more likely. The Baroni family is a rat's nest of divorce, bitterness, ambition, and greed. Junior's soon-to-be-ex has Mob connections, and her brother is in prison for an earlier attempt on Baroni the elder's life. Polo doggedly pursues the case as the bodies pile up and the threats to both his life and Jane's increase in intensity.
