As Hurricane Irene bears down on New Jersey, the Housewives flee to the sunny, golden coastlines of California. With their stilettos, fake tans, and dried sausage, they pile into cramped RVs for the road trip to end all road trips. With tensions between Caroline, Jacqueline, and Teresa at an all-time high, it's a constant struggle to keep the peace. Meanwhile, Teresa confronts Kathy over her "stolen recipe" accusations and sister-in-law Melissa attempts to show Teresa the error of her ways.

The great Jersey caravan stomps its way through Napa for a business meeting with a local vineyard. But all work and no play make the Housewives dull gals, and too much horseplay threatens to ruin the deal for good. And in a shocking moment of truth, one phone call could change Teresa's life forever.
