Set against the backdrop of a beautiful garden in the heart of London, this contemporary fairy tale revolves around the unlikely friendship between a reclusive young woman and a cantankerous old widower. Bella Brown is a beautifully quirky young woman who dreams of writing and illustrating a successful children’s book. After she is forced by her landlord to deal with her neglected garden or face eviction, she meets her match, nemesis, and unlikely mentor in Alfie Stephenson, a grumpy, loveless, old man who lives next door who happens to be an amazing horticulturalist.

Complications ensue when an overworked couple decides to hire a "wife" — someone who can run the household for them with complete autonomy — but she's a little too attractive for comfort.
