Five noted athletes, including an American high-jumper and a Russian sprinter, have disappeared. Fireball is asked by authorities to look into it. He quickly is doped and captured by a scientist named Doctor Bojor who is developing a pill to "increase man's strength, stamina, and lifespan". The mad doctor needs the captured athletes to test his formula and uses torture to make them take part.
