When We Were Kings is a documentary about the historic 1974 "Rumble in the Jungle" heavyweight championship boxing match in Zaire (now Democratic Republic of Congo) between the underdog Muhammad Ali and the formidable George Foreman, exploring the cultural, political, and racial significance of the event, Ali's charisma, and his role as a proud Black ambassador, interweaving archival footage of the fight, training, and the accompanying Zaire '74 music festival with modern interviews.
