One year after the murder of columnist Jamal Khashoggi, FRONTLINE investigates the rise and rule of Crown Prince Mohammed bin Salman (MBS) of Saudi Arabia. In a never before seen or heard conversation featured in the documentary, the Saudi Crown Prince addresses his role in Khashoggi’s murder exclusively to FRONTLINE correspondent Martin Smith. Smith, who has covered the Middle East for FRONTLINE for 20 years, examines MBS's vision for the future, his handling of dissent, and his relationship with the United States.
