Mother and daughter Magdalena and Mila acquire a house in the White Valley of Cornwall in the summer of 1954. Magda has grand plans to restore the house to its former glory as a venue for glittering parties. Her grown daughter, Mila, just wants to escape the scandal in her past and make a safe and happy home for her little girl, Janey, a solitary, precocious child blessed with a vivid imagination, much of which she pours into stories about her magical plush toy, Rabbit. But Janey's rabbit isn't the only magical being around. Legend has it that an enchanted white hare may be seen running through the woods. As Mila, her mother, and her young daughter adjust to life in this mysterious place, they will have to reckon with their own pasts and with the secrets that have been haunting the White Valley for decades.
