The moment where American sprinters Tommie Smith and John Carlos raised their gloved hands in defiance on the podium at the 1968 Mexico City Olympics is one of the most memorable images in sports history. But there is a third man in the photo, the white Australian who finished second to Smith and ahead of Carlos in the 200 meters. His name is Peter Norman, and he stands in quiet solidarity with them. Norman’s story is retold in this film with passion and perspective.
