Kosta, a man with a mysterious past, runs an old bookshop. In the shadow of books, he solves cases too tough for the police. By his side are Ilonka, the only flame of innocence; Peter, an uncle with a clerical collar and stained hands; Despina, the enigmatic Madam D.; Volodja, a boxer who fell too soon; Vida, the silent witness of hidden truths; and his brother Sandro, a lawman with a weak heart.
When Kosta crosses the line for Sandro, the world falls and sin is the only language still spoken.
