In the series premiere, Ladies of London explores the world of Britain's high society. British natives and American transplants rub shoulders together but must adhere to strict unwritten rules of engagement. Having a title may get you respect but having money does not always give you the highly coveted status quo. True to form, the Brits and Americans may speak the same language but have different ways of interpreting their place in this tightly knit society.

While the women recover from the first Polo event of the season, Noelle and her boyfriend Scot grapple with his legal woes and discuss moving back in together. Meanwhile, Caprice hits the tabloid headlines when she reveals a carefully calculated secret. The ladies prepare for the Serpentine Party, the biggest social event of the summer. However, Scot's notorious front-page divorce may prevent Noelle from getting a ticket.

Meanwhile, fashionista Annabelle puts on a runway show and Noelle and Scot hit yet another roadblock in their relationship. Royal friend of the ladies Julie Montagu invites the women to her aristocratic family's Mapperton estate for a weekend of bonding.

The Ladies take a trip to the regal Mapperton estate, home to the Earl and Countess of Sandwich, with the hope of mending the group back together. A weekend full of skeet shooting, croquet, British flower gardens and cream tea in the countryside are a sure mix to make anyone forget their woes, but with this group of ladies, things may suddenly go awry.

Meanwhile, Annabelle continues her risky training for a charity horse race, all while grappling with third trimester hormones, Caprice takes on a new By Caprice model for a huge photo campaign.
