On October 2, 2018, Washington Post columnist Jamal Khashoggi walked into the Saudi consulate in Istanbul, Turkey. He never walked out. Within a matter of days, it was revealed that he had been murdered and dismembered by a 15-person Saudi hit squad. What role did Saudi Arabia’s new crown prince, Mohammed bin Salman, play in orchestrating the murder that shocked the world? And who is this young and powerful member of the Saud dynasty — portrayed as a modernizer with the firm support of President Donald Trump?

One year after Khashoggi’s killing, FRONTLINE presents The Crown Prince of Saudi Arabia — an epic, investigation into MBS’s ties to the murder, his relationship with the U.S., his handling of dissent, and his vision for the future of Saudi Arabia. This two-hour program features on-the-ground reporting from veteran FRONTLINE correspondent Martin Smith (Bitter Rivals: Iran and Saudi Arabia), who has been covering the Middle East for FRONTLINE for nearly two decades.
