Jim Randall, an office clerk, was recovering from injuries sustained by trying to protect Linda Thompson's brother Andy from being beaten up by a gang lead by mobster Duke Cazzini. He ends up not only getting himself punched in the face, but also losing Linda's respect because of his delay to act and inability to protect. While he was resting, however, he is visited by Atlas, the "Greek God of Strength." Atlas, feeling sorry for Randall, teaches him his "strange, secret exercises." Randall goes out to his Uncle Hank's ranch in Arizona, where he tries the exercises and gains super strength and agility. He then returns home, with a new costume and his new abilities and defeats Cazzini, who had continued to bother Linda and Andy in Randall's absence.
