1870. The Prussians are encircling Paris. Europe’s capital of decadent pleasure is becoming a prison, as winter sets in and starvation looms. Jean-Jacques Allix promises to lead all those who follow him, to save the city itself. Painter Hannah Pardy, his young English lover, combines her two passions – love for Paris and devotion to its saviour – in her work, as she attempts to reflect, in her brushstrokes, her commitment to the capital and the man battling to save it.
