Mademoiselle tells the story of this heroic young woman who is part of this generation of men and women who fought to abolish slavery with their ideas of freedom and equality for all...

In his fight, Mademoiselle would receive considerable support; that of Rodolfo, his everyday friend whose status as an experienced activist she ignored. Together, they will win the battle, the battle to see the barriers between social classes fall and to be able to love each other freely...
