On October 1, 1975, Muhammad Ali and Joe Frazier meet for a third time in the Philippines, in a fight organized under the patronage of Imelda Marcos and staged as a national spectacle. The film pulls together archival fight footage, training camp material, and behind-the-scenes access to trace the buildup between two fighters who already despised each other after two brutal prior bouts. Ali's pre-fight taunts and Frazier's simmering resentment are given room to play out, and the film uses that personal animosity to explain why both men kept pushing themselves past reasonable limits once the bell rang. The Manila setting itself, complete with the Marcos regime's involvement in bringing the fight to the country, gets treated as part of the story rather than a backdrop. What emerges is an account of a fight both men later admitted nearly killed them, with Frazier's trainer stopping the bout before the final round and Ali collapsing from exhaustion moments after being declared the winner.
