The sisters did it for themselves in the red light district of Amsterdam. Louise and Martine Fokkens are identical twins. For over fifty years, they have been working as prostitutes. They broke free from the control of pimps, ran their own brothels, and established the first informal prostitute union. They are familiar faces in Amsterdam's red light district, but soon they will bid farewell. "Ms. Fogg" is a portrayal of these outstanding women and also the history of the Red Light District over the past fifty years.
