It's 1925. Attractive and strong-willed 23-year-old Isla Scott leaves her job as a nurse in Edinburgh to return to her hometown of Edgemuir and take up a vacancy at Dr Lorne's fashionable spa, where she is reunited with her handsome brother, Boyd. Revelling in her new role and being close to Boyd, all seems well for Isla and the Scott family. But the siblings soon find that romance threatens to cloud their future. Boyd is bowled over by pretty new waitress Trina Morris, but is she playing games with his affections? Meanwhile, the rest of the spa is falling under the spell of a new doctor, Grant Revie...but will Isla?
