When Drake is shown a photograph of a young girl who is the victim of drugs, he sets out for the Middle East to break up the ring supplying opium. He is aided by an American agent, Sandi Lewis.

Together they trace the source of the drugs, with the help of a courageous little man.

Hardy assigns Drake to fly to the Middle East to find Vanessa Stewart, a beautiful girl wanted for espionage. Posing as a Baltic agent, Drake persuades her to accompany him before the British find her. A subplot comments drily on the ethics of espionage.
