Set against the backdrop of a beautiful London garden, the story is a contemporary fairy tale. Facing eviction in a month if she can't resurrect the dying garden in her backyard, reclusive librarian Bella Brown meets her grumpy next-door neighbor, who happens to be a talented horticulturalist. As the two form an unlikely friendship, Bella begins to wonder if she can revive both the garden, and her dreams of becoming a children's book author.
