It is suspected by the US government that defense plans for the soon-to-be-opened Panama Canal had been stolen by a notorious Russian spy but not yet sent out of the States. It falls to Jimmie Calvert to track down this operative and get the plans back before they can fall into the hands of those who want to destroy the Canal before it even starts.
