Passport to Suez, a 1943 spy thriller directed by Andre DeToth, follows a former jewel thief, who bears the nickname "The Lone Wolf" (Michael Lanyard), as he works for the British government in hopes of destroying an evil German spy ring. While on this mission, The Lone Wolf responds to a request to meet a British diplomat only to find that the note was in fact a setup. Instead, the diplomat was taken hostage and faces execution unless The Lone Wolf agrees to provide secrets of the British government. Rather than follow through with his commitment, however, he alerts an American spy to the situation and agrees to relay any information available regarding the hostage takers' ultimate mission. The Lone Wolf must move carefully so that he might prove convincing in his role of stealing secrets, while at the same time ensuring that no permanent damage comes about as a result.
