Nana tells the story of Nana Coupeau's rise from streetwalker to high-class prostitute during the last three years of the French Second Empire. Nana first appeared near the end of Zola's earlier novel Rougon-Macquart series, L'Assommoir (1877), where she is the daughter of an abusive drunk. At the conclusion of that novel, she is living in the streets and just beginning a life of prostitution.Nana opens with a night at the Th��tre des Vari�t�s in April 1867 just after the Exposition Universelle has opened. Nana is eighteen years old, though she would have been fifteen according to the family tree of the Rougon-Macquarts Zola had published years before starting work on this novel.
