On April 7, 2007, at UFC 69 in Houston, Texas, Long Island's Matt Serra accomplished his dream of becoming UFC welterweight champion. Serra, a huge underdog in the fight, promised everyone he would shock the world that night. He did just that when he knocked out Canadian superstar Georges St-Pierre in the first round. Ten years later, it remains the biggest upset in UFC history. Serra, trainer Ray Longo and others who were there that night share the stories from that week, that fight and its lasting impact on them, on Serra and on the UFC in this documentary.
