Agents of a mysterious foreign power (for once, not the People's Republic - or, at least, not that they're admitting) abduct Nelson's sister Edith. He must supply them with a map that details the precise location of defensive missile silos located on the sea bottom, or they will kill her. Will he sell out his country for his family? It appears he'll have no choice - but appearances may be deceiving.
