Harry Diamond has been working a case at his agency involving a Gold Medallion and a treasure map supposedly showing the location of Inca Gold. Just recently, he has come up missing. Now, his kidnappers are searching for his nephew, Woody Alfred to see if he can shed further light on the items they seek. After a few close calls at being captured by these people, Woody asks his friends, Andrea Richards and Sandra Allenbrooke to help him find out what is going on. But just as they are getting close to finding out, they are kidnapped themselves by "Uncle Sam" and whisked away to a secret mountain retreat. While there, they find the government is also interested in the treasure of gold, but for different and complex reasons.
