Having inherited a big estate on the outskirts of London, Octavia is lighthearted as she sets out to see the property. Upon arrival, she comes across two girls-a smart, quiet girl who reminds her of a storybook princess, and her younger sister, a tomboy who looks like a tiny fairy. Confused, Octavia is led by the sisters to meet their uncle Edward Barraclough, who believes she has come seeking a job as a governess... Little does he know she's actually the new owner!
