Daisy, Griff, and Louis's whole family are living under the same roof, a situation made even more challenging by relationship troubles. Louis makes a last-ditch attempt to save his marriage, while Griff tries to rescue his romance with Gus by coming out online. At rival winery Shimmering Lake, Marissa plots to bring Oakley down a peg by hiring flashy French vintner Philippe Bidois—Tippy's cousin.

Daisy and Louis discuss what happened in Queenstown; after Tippy leaves, the crew discover her new blend is incredible; Louis decides to declare his feelings for Daisy; an old friend turns up with news that will rock everything to the core.

Harvest is fast approaching, so Tippy gives everyone a lesson in the delicate art of grape-picking. The problem is everyone gets too distracted to focus. Daisy goes off on a walk with Nic and meets handsome local doctor David. Vic asks Louis to help him out with a potentially serious legal problem. And Gus and Griff decide to go on their first romantic trip away together.

Daisy and Louis attend Marissa's book club, but Daisy gets the wrong book; Daisy gets tongue-tied meeting David's daughter for the first time; Louis discovers Hilary's eyesight is failing, which caused her vintage to fail, too.

The crew head to Queenstown to support Tippy at a wine conference; Daisy and Louis end up sharing a dodgy motel room; Louis overhears Philippe arguing with another vintner, confirming his suspicions; he plots with Daisy to expose him.

Facing financial pressures, Oakley Wines invites the bank manager, Mr. Talbot, for a tour; their frost-fighting fan explodes ahead of a frost forecast; Tippy goes old school by heating the vineyard with flaming pots and help from the community.
