Tommie Smith comes in first place for his event, beating out his fellow American Olympian, John Carlos. At their awards ceremony, both men give the black power salute. 

Tommie Smith talks about black unity in an interview. 

Both runners walk on the track after the ceremony wearing no shoes, just black socks, to signify their poverty. 

Lee Evans, James Hines, and George Foreman are shown boxing. 

Black American Olympian Barbara Ferrell discusses both her time at the Olympics in Mexico and Smith and Carlos' black power "thing." Ferrell is shown running in her competitive event.
