Plot

In Italy, Indy's espionage work takes him behind enemy lines where he embarks on an important propaganda assignment that he hopes will bring a swift end to the war. Along the way, he engages in a comic rivalry with Ernest Hemingway over the affections of a beautiful Italian girl. After being wounded in action, Indy is transferred to North Africa where he joins the French Foreign Legion. While trying to uncover the identity of a traitor in his own ranks, Indy battles hostile Berber tribesmen and engages in an innocent flirtation with author Edith Wharton.
