When world-class thief Goldar and his gang steal a golden statue of Buddha, they bring the wrath of the international police force down upon them. Bungling wannabe private detective Kuruma Joe tries to beat the professionals to the punch, little knowing that his lackadaisical apprentice Takeshi is secretly the superhero, Hurricane Polymar!
Onitora, the director of the International Secret Police Agency, looked forward to making his favorite son Takeshi a top-notch criminal investigator. Takeshi was given Spartan training, which turned him into an all-around sportsman as well as martial arts expert. However, Takeshi's attitude toward crime-fighting was so incompatible with his father's that the furious Onitora disowned him. For a while Takeshi investigated crime as a lone wolf; then he became a private detective's assistant and general handyman. Secretly, however, Takeshi obtained from a scientist a new artificial polymer, polimet, that was far stronger than steel. With this polimet Takeshi transformed himself into Hurricane Polymar, an invincible costumed hero.
