 In the red light district of São Paulo, lives of loneliness and hopeless people cross in a Saturday night. The low class workers Toninho (Ney Latorraca) and his friend Giba (Roberto Bolant) leave the periphery with their monthly salaries expecting to have sex. They meet two prostitutes, Marcela (Marlene França) and Ivete (Betina Vianny), and along the night in a very low budget hotel, their relationships deteriorate and nothing happens as planned. Meanwhile, the country man Pedro (Ewerton de Castro) arrives trying to bring her former fiancée and presently pregnant prostitute back to Laranjeiras, their home town.
