Nails tells the story of Lina, Vanessa, Irene and Marilís, four women from different backgrounds and of different ages who meet in a nail salon. Their repeated encounters spark a unique friendship, turning them into partners in crime and influencing the most important decision of their lives: to rebel against their reality and reject who they have become. What happened to their right to choose? Are they victims of what is expected of them? This non-conformism, paired with a feeling of sisterhood, leads the protagonists to create ‘The Free Women's Club' - a safe space intended to help other women solve their problems.
