It's all about the 'old vines' for team Plonk as their Barossa adventure continues and nothing says tradition quite like the Barons of the Barossa. Josh, who is desperate to be a part of the old guard, is tipped off by a Baron on how to join. Plonk's Barossa luck finally changes when they land an exclusive interview with Yalumba icon Robert Hill Smith.

While filming in the coastal wine region of McLaren Vale team PLONK are joined on set by an unexpected visitor, the Brand Manager for Lexus. Contractually obliged to feature Chris and the sponsor car, Nathan has just one problem...Chris can't drive.

The unexpected death of Herb, Plonk's camera operator, throws the final days of shooting into turmoil. Not wanting to let a day off go to waste, Chris looks to familiarize himself with the famous Cabernet Sauvignons of the Coonawarra. Josh reacts to Herbs passing in a more spiritual way, turning to local saint Mary MacKillop for guidance.
