Al-Usta (Bahbah), the barber, lives in the city of Baghdad, and one of his customers, Sheikh (Makhlouf), tells him: Shahbandar al-Tajjar said that he had a son who was constantly ill, named (Qamar al-Din). He suggests that he get him a slave girl, perhaps she will bring joy and happiness to his heart. Indeed, his father buys a slave girl named Baddour. She discovers that the cause of his illness is his love for (Shams), the daughter of the judge, so Badour suggests that he convince his father to guide her to the judge so that she can be the messenger of love between (Qamar) and (Shams), and Bahbah helps her in that. He knows the judge. By order, he imprisons them all and they try to escape.
