1920s. When her father dies, Ellie Douglas has little option but to go into service. Her position takes her out of the life of Frank Rafferty—childhood friend and now a member of one of Glasgow's notorious gangs—and into the world of Evander Tait—son, heir and black sheep of the Tait household. These two men dominate Ellie's entire life. No one approves of her friendship with Evander and the bond she shares with Frank is misunderstood by everyone. Both relationships, for very different reasons, threaten to tear her apart.
