London, 1866. Greek heiresses Marie, Maria and Aglaia - our Three Graces - have high artistic ambitions, which are consistently dismissed thanks to their accents, foreign habits, and status as women. Seeking to take part in a male-only art competition, they enlist the help of etiquette expert Henry in order to “become British” and impress art critics and London society alike. At a gallery, a chance encounter with Pre-Raphaelite artist Dante Gabriel Rossetti could be just what they need to make a name for themselves.
