Holt plays a karate expert who takes possession of a coin that is the alleged key to a supply of platinum smuggled out of Germany. He enlists the help of his friend Blaine, who later double-crosses him. Further investigation finally leads Holt to Shiga, the brain behind the smuggling
operation. The two clash head on in grand karate style, and, naturally, the better man (Holt) emerges victorious. Holds some interest because of location scenes filmed in Japan.
