On a couples' trip in Sicily, Harper, Ethan, Daphne, and Cameron spend an awkward first day sizing each other up. As Tanya arrives with her new assistant Portia, Dominic fields questions from his father Bert about his wife’s absence, while his son Albie plays neutral. Meanwhile, hotel manager Valentina tries to keep locals Mia and Lucia out of her establishment.

Though Harper bristles at Ethan’s suggestion that she’s overly critical, her suspicions are raised when Cameron and Daphne claim they never fight. Meanwhile, Lucia and Mia take full advantage of their newly acquired hotel guest status, Albie and Portia (sort of) connect over dinner, and Tanya enlists Greg to help her live out her perfect day in Sicily... on a Vespa.

After promising to have a more positive attitude, Harper gets looped into a side excursion with Daphne – leaving Ethan and Cameron behind for some bro time. On her own for two days, Tanya seeks advice from a local tarot reader and summons Portia back from sightseeing with the Di Grassos. Later, Albie questions whether his father truly respects women.

When Tanya receives an impromptu invite from dashing ex-pat Quentin, Portia finds herself spending the day with his beguiling nephew, Jack. After returning from her trip with Daphne, a relieved Harper is blindsided by a piece of evidence from Ethan’s night out. Meanwhile, a suddenly guilt-ridden Lucia tries to keep Mia on a righteous path.

Still doubting Ethan, Harper gets real during a wine tasting trip with Cam and Daphne. Meanwhile, Tanya and Portia embark on a whirlwind two-day excursion to Palermo with Quentin and Jack, Albie navigates a misunderstanding with Lucia, and Valentina decides to make a staffing change to get a flirtatious Rocco away from Isabella.

Hoping to help Lucia, Albie asks Dominic for a karmic payment. With Portia still unreachable, Tanya grows increasingly wary of Quentin's motives. Consumed with doubts, Ethan confronts Cam... and gets unexpected advice from Daphne. After an eventful night, Valentina gives Mia a chance.
