Professor Akron is an inventor based in Singapore who creates the Eradicon; a jewel like filter for a laser weapon that dramatically improves its power and range as well as the ability to stop engines over long distances. Akron is given three days to accept a "blank cheque" from a criminal mastermind known as the Golden Dragon, but he contacts Interpol who arrange to send New York private detective Joe Walker and New York Police Captain Tom Rowland to Singapore to protect the professor, his attractive daughter and the Eradicon.
