Following a whirlwind romance, they marry and fall headlong into a Paris that is experimenting with new forms of living, thinking, and creating. Soon after marrying Francis, Gabriële meets Marcel, another young artist, five years her junior. Soon, Francis, Marcel, and Gabriële are all involved in a fervent affair that will change the course of art history and redefine the avant-garde.
