Fanny Logan tells the stories of her two friends, Linda Radlett and Polly Hampton and their various pursuits of love. Linda falls in love with banker, Tony Kroesig, and defies all parental wrath and advice to marry him. Meanwhile Polly, daughter of Lord and Lady Montdore, is home from India but has no intentions of marrying the men presented to her. Linda leaves her husband for communist, Christian Talbot. Her bother Matt runs off to fight in Spain. Fanny makes a good steady marriage with Alfred Wincham while Polly announces her intention to marry her newly widowed uncle, Boy Dugdale.

Since Lord and Lady Montdore cannot stop Polly's wedding to Boy Dugdale, they cut her off without a penny. Linda meanwhile is throwing herself into Christian's work and the Communist cause. Polly returns to have her baby, but her marriage to Boy is not happy. When her baby dies, her old friend Lord Paddington comes to the rescue. Linda meanwhile realises that Christian is more interested in the cause than her, so she leaves and meets Fabrice, the Duc de Sauveterre on her journey home. They have a year of bliss before the Germans march into Paris, and Linda is forced to return to London.
