Detective Jo Walker (Tony Kendall) and New York Police Captain Tom Rowland (Brad Harris) are sent to Singapore to protect Professor Akron (Ernst Fritz Fürbringer) and his latest invention - a laser filter than can be used to shut down electrical engines from miles away, which means a weapon of mass destruction if it falls in the wrong hands. But they are outnumbered in a number of fights with the baddies, and the Professor ends up the prisoner of the mysterious Golden Dragon. So, the new mission is more difficult: to rescue the Professor, protect his beautiful daughter, and safeguard the filter. The Golden Dragon proves to be very powerful, and commands a small army of gun-toting men, and whip-cracking women.
