Maria, a young girl from a remote village of Brazil, whose first encounters with love had left her heartbroken, goes to seek her fortune in Switzerland.

She then decides to become a prostitute and ends up in a brothel on Rue de Berne, the heart of Geneva's red-light district.

There she befriends Nyah who gives her advice on her "new profession" and after learning the tricks of the trade from Milan, the brothel owner, she enters the job with her body and mind shutting all doors for love and keeps her heart open only for her diary.

Months pass and Maria grows into a professionally groomed prostitute who not only relaxes her clients' minds, but also calms their souls by talking to them about their problems.

Her world turns upside down when she meets Ralf, a young Swiss painter, who sees her "inner light".
