HBO follows Brandon Rios for 2 days before his 29th fight as an undefeated professional boxer. His fight is not only British boxer John Murray, but also to make weight so he can defend his lightweight title. “Bam Bam” looks like a person suffering from a terminal disease in the footage right before the weigh-in.
