Edinburgh, 1911. When intelligent Elinor Rae leaves her crowded tenement family home to become a maid in an exclusive ladies club in the idyllic Primrose Square, she doesn't look back. Two years later and Elinor is still in love with the square, and now also with Stephen Muirhead, her evening tutor. But it all goes wrong. Elinor's head is turned by handsome Barry, and when he signs up to the war effort without thinking of her, she is devastated and bitterly regrets her mistake. But has Stephen really put Elinor behind him?
