Lisa Vanderpump is back and once again curating bespoke experiences for eager guests. This time around an Italian castle is the backdrop, Stassi Schroeder returns, and there is a mix of familiar and new staff, ready to impress.

A group of reality stars and global athletes arrive at the castle for some rest and relaxation. One staff member would rather play than work, which causes tension among the staff, and love is in the air for some couples, but toxicity is real for others.

A night of arguing leaves some staff wary of Siadi and Sianna's relationship. `The Secret Lives of Mormon Wives' arrive at the Castle, Sam and Marciano are especially intrigued, but an innocent drinking game ends in hurt feelings and deception.

Andre has a change of heart about his relationship with Gabriella and seeks Lisa's advice. The staff enjoys a night out at a lake, but when one couple decides to intervene in another's argument, fireworks fly in the sky and through the castle.

Marciano and Hannah find themselves in hot water with Lisa for their recent actions. Grace decides to act on her crush, and when a new group of beautiful women arrive at the castle, Tyler finds himself in the doghouse with Lexee.

A botched breakfast service upsets Chef Anthony, Sam finds potential romance and Dominic turns his attention to another Staffer, much to Graces' dismay. A meltdown in Lisa's office empowers Sianna to make a decision about her future with Siadi.

Lisa plans for a birthday party planned at the castle and the front of the house clashes with the back of the house after an imperfect dinner service. An argument over a tattoo sends Beau and Stassi spiraling during a family visit.

Some new faces in the castle shake up the old dynamic within the staff quarters and a budding romance blossoms. Sam and Siadi reach a breaking point with each other and when a group of guests ghost hunt in the castle, Stassi is ready to oblige.

Siadi's lack of emotion rubs most of the staff the wrong way, leading to a major group confrontation. Stassi and Beau decide to cook everyone a decadent thank you meal; and tensions within the kitchen staff boil over in the last days at the castle.

The final group of guests celebrate a surprise engagement party, but one of the staff members makes them extremely uncomfortable and Lisa is enraged. As the summer season comes to the end, the most exemplary employee is recognized.

After an Italian summer of high stakes, scandal, and celebration at Castello Rosato, Lisa Vanderpump reunites her staff for one final night of reckoning—only this time, she’s handing the hosting reins to her VIP guest, the one and only Stassi Schroeder.
