In a naval escapade spanning coastal California to the Panama Canal, Operator 5 tackles a most cunning adversary–Chief secret agent of the Yellow Empire, Kara Vizna, the most dangerous, and most beautiful, secret agent alive.

Only Jimmy Christopher, known in the Intelligence department as Operator 5, has the wherewithal to defeat this devious reign of terror.
