Sir Leonard Wallace, Chief of the Secret Service, sends one of his
agents to Germany to obtain vital information from the Baroness von
Reudath. Foster is told to feign infatuation with her, but the lines
between reality and pretence soon blur as a result of his growing
affection for the baroness. Before long, Foster becomes prey to the
insane jealousy of the tyrannical Marshal von Strom: Foster suddenly
disappears and the baroness is charged with treason - the punishment for
which is death. Can Wallace use his cunning to foil von Strom's
treacherous plans and rescue the distressed lovers before it's too late?
