When her father is declared missing in action during World War I, Elsie Wrigth (Florence Hoath) goes to live in England with her cousin Frances Griffiths (Elizabeth Earl) for whom the topic of fairies is forbidden. Immediately, the girls discover the winged creatures in the garden and photograph them for Frances's startled parents. This leads to another kind of adventure for the girls. They become the toasts of London as Sir Arthur Conan Doyle (Peter O'Toole) and Harry Houdini (Harvey Keitel), who have seen the photographs, escort them around town. Mildly villainous reporters chase the girls and curious spectators invade their garden after the pictures are printed publicly.
