At Agent K7's headquarters, Special Agent B9 has been requested to report for a new assignment. Two days ago, a valuable map was stolen from General Staff headquarters, and it must be recovered immediately. There is reason to believe it hasn't yet been carried out of the country. Agent K7 has a dossier of the case which has been prepared for B9, containing all of the facts. Miss Yvonne Durrell will act as B9s assistant.
