Amy Robinson and her fiance Matthew are struggling to resist the temptations faced by a soon-to-be-wed couple. To avoid these, Matthew throws himself into a new job that takes him away from Amy, and she goes to work in an exclusive new dress shop, where she meets Mary Maitland. Only once their friendship has developed does Amy become aware that Mary is the daughter of her mother's enemy. As her relationship with Matthew deteriorates, Amy becomes increasingly attracted to Mary's cousin Paul Ross, which does not please Mary, who wants him for herself.
