The current trend to render prostitution a profession "as any other" is belied by women who were themselves prostitutes. With clarity and courage, the women in this film reveal the hidden face of that so-called "sex work". They are 22, 34 or 48 years old; they live in Montreal, Quebec and Ottawa - They have recently given up prostitution, or are trying to escape it. These women are leading the bitter fight to turn their lives around and it is a long and lonely struggle fraught with difficulties. Shot in a Cinéma Vérité style, The Fallacy (L'imposture) takes us to the heart of their realities.
