Set in the 1900s, when the British Secret Service was a new, unofficial arm of military activity, the series features Captain Robert Virgin - an officer and a gentleman who fights as a man of honour. Armed only with intelligence, ingenuity, physical strength and abundant charm, Virgin faces every sort of peril as he defends King and country - from industrial espionage to anarchist bomb plots, assassination attempts to kidnapping.
