This episode looks at how the family stays in power. The film features some of those who have worked for Saudi princes. They describe how the wealth allowed lives of privilege and pleasure out of the spotlight, but the growth of social media has meant Saudis are getting increasing insight into the behaviour of their rulers, including their transgressions. With this crucially important country facing a historic crossroads, the programme asks what the future holds for Saudi Arabia and the rest of the world.
