Summary: It's 1974, Muhammad Ali is 32 and thought by many to be past his prime. George Foreman is ten years younger and the Heavyweight champion of the world. Promoter Don King wants to make a name for himself and offers both fighters five million dollars apiece to fight one another, and when they accept, King has only to come up with the money. He finds a backer in Mobutu Sese Seko, the dictator of Zaire and the "Rumble in the Jungle" is set. A musical festival, featuring the America's top black performers, like James Brown and B.B. King, is also planned.
