Watch Sadisflix. Nader (Samir Ghanem) and Al-Zanati Khalifa (George Sidham) are two friendly doctors, but they are very different from each other. The son of the dean of the Faculty of Medicine succeeded in his people's respect for his father and took his work for quick profit and wealth at the expense of professional ethics. He spent seven years in Upper Egypt and devoted himself to the Abu Qarat department, and between the two there are dialogues about ethics and society, and about their differences.
