About men who are courageous enough to risk their lives undertaking challenges, sports-related and not, that are at the limit of human capabilities. The film shows one young man launch himself out of an airplane without a parachute, which will be given to him in-flight by another man. This is probably the first time a similar event has been filmed. Other undertakings include the cliff divers of Acapulco, a lion tamer from Thousand Oaks, California and a pilot, Art Arfons, who can reach 526 miles per hour on a Bonneville.
