This is the story of four muses. Adele: passionate, fierce, obstinate. The daughter of a bourgeois family in 1900s Vienna, she rails against the strictures of her class and yearns for freedom. Gertrude: spirited, single-minded, possessive. The sister to budding artist Egon Schiele, she longs for an exciting life away from their tempestuous family home. Vally: determined, independent, proud. A model for celebrate artist Gustav Klimt, she has carved her way out of poverty and is now forging a brave new path for herself. Edith: Adele's sister. Quiet, conventional, loyal. Or is she? Four flames, four wild, blazing hearts, longing to be known. All four will become muses to the charismatic but controversial artist Egon Schiele. In an elegant bohemian city like Vienna, everything seems possible - until an act of betrayal changes everything. For just as a flame has the power to mesmerise, it can also destroy everything in its path.
