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