The story begins with Beatrix Potter nervously packing her portfolio and narrating that she is a London spinster, and that her ambition to become a children's author meets with wide disapproval. She and her chaperone, Miss Wiggin, visit the publishing house of Harold and Fruing Warne, who decide to publish her The Tale of Peter Rabbit. Beatrix is thrilled and returns home, taking a drive through the parks to celebrate first. However, it is revealed the Warne brothers think her book is ridiculous and will no doubt be a failure. The only reason they agreed to publish it is because they promised their younger brother, Norman Warne, a project.
