Indigo Tea Shop owner Theodosia Browning investigates after a body turns up in a wine barrel at a fancy wine-tasting party in South Carolina.

A fancy wine-tasting party at the upscale Knighthall Winery, just outside of Charleston, takes on a bitter aftertaste when the body of the owner's son is discovered in one of the wine barrels. When he turns to Theo for help, she discovers that everyone at the winery seems to be lying through their teeth. Theo has her pick of suspects, and it looks as if the killer has her over a barrel.
