Tamra and Simon Barney celebrate their ten-year wedding anniversary with a weekend getaway in Napa, and they invite Vicki and Donn Gunvalson to join them. While Tamra and Simon enjoy a romantic weekend of wine tasting, grape-stomping and gourmet dining, Vicki struggles just to be civil to Donn. Envious of Tamra and Simon's relationship, Vicki concludes that her "love tank" is empty and she's uncertain if Donn can fill it. Although her husband, Matt, is still in her house, Jeana Keough is making an effort to re-build her life post-separation with the encouragement of her family and her trainer, John Ellis. Gretchen Rossi and Jeff attend the Indianapolis 500. With his history in the automotive and racing car industry, Jeff's status provides access and privilege that very few people have at the races. Gretchen rubs elbows, exchanges a few kisses, and rides along with the Indy 500 royalty. Meanwhile, a horrible turn of events threatens Lauri Peterson's fairytale life with her husband, George.
