To Barcelona, Forever begins five months later and follows Erica and Anna as they are happily navigating new chapters in their lives.  This time the friends find themselves traveling outside the city of Barcelona to a charming village where a misunderstanding leads to unexpected romance for one of them.

Katie agrees to join her brother Dan and his girlfriend Luciana on a trip to Peru. Dan plans to propose to Luciana in a grand way at Machu Picchu at the end of the week and needs Katie's Spanish speaking skills to ask Luciana's Peruvian father for his blessing. However, when Luciana's friend, Chef Carlos, arrives, he accidentally ruins each proposal attempt. Refusing to give up, Katie does everything in her power to make this proposal happen, until Dan calls it off. Katie must lean into Chef Carlos' spontaneity to not only save the day and the proposal, and Carlos may just win Katie's heart too!
