Daniel Browning Smith's search for real life superhumans takes him to Fond du Lac, Wisconsin to meet Tim Friede, a human guinea pig, who allows some of the world's deadliest snakes to bite him to record the results for medical research to reduce the deaths caused by snakebite throughout the world. Daniel meets up with Dan Meyer of Hartselle, Alabama, one of the world's greatest sword swallowers, who swallows a sword heated 1500 degrees red hot and multiple swords at once while being x-rayed at Vanderbilt Medical Center in Nashville TN; Garry "Stretch" Turner of London, England whose rare medical condition gives him the world's stretchiest skin; and Yves Rossy of Geneva, Switzerland who flies with a high-tech, jet-powered wing strapped to his back that is controlled by precise movements of his body.
