Taylor OBrian, founder of “Off the Beaten Path”, takes small groups on wine country tours of romantic Sonoma County. Friends are everything in the tour business, so Taylor is happy to guide investors to the winery owned by her friend Tim Slade. But vintage turns to vinegar when an FDA inspector is found floating face down in one of Tims vats of squished grapes. Tim is arrested on suspicion of murder, and Taylor and her friends rally to prove his innocence. But its not an easy task, especially since the winery proprietor's acidic sense of humor tends to reap a harvest of sour grapes. Taylor's investigation is withering on the vine until she discovers that Tim's girlfriend, Mandy, is having an affair with a self-help guru. But before she has a chance to confront Mandy, Taylor finds Tim standing over the body of the dead guru. This tart turn of events sends a bottle shock through Sonoma. Might Taylors friend really be a Zin-ful killer? If so, could Taylor be the next victim? The tour guide and her friends come to realize that the true murderers scent is obscured by an unsavory bouquet of red herrings.
