It’s 1870 and Paris is under siege. The lights are going out all over the city, but one man seems to shine like a beacon in the shadows. Jean-Jacques Allix promises to be the leader the people need, to save the city itself. Painter Hannah Pardy, his young English lover, believes in him utterly; taking up arms for his cause, she is drawn into the heart of the battle for Paris. But as the darkness and panic spreads it is harder and harder to see things as they really are, and Hannah struggles to separate love from self-interest and revolutionaries from traitors.
