The Roman businessman Fausto Di Salvio can no longer stand his work and his sloppy and emotionless way of life. The chance to escape from this "prison" occurs when the news of the death of his brother-in-law, Oreste Sabbatini, known as "Titino", arrives from Africa. Fausto, with his employee Ubaldo, his firm's accountant, leaves immediately to Angola in search of Titino, a journey that will take many months of travel and will involve them in many adventures. They follow in Titino's tracks, but it seems that he cannot be found. From what they learn by speaking to people who have met him, Titino appears to be a man of many resources who has left behind him many people crazy of him, but even someone who was cheated by him and who would be glad to lay hands on him.
