Arlo is an armadillo who is always up for adventure. His grandfather, Augustin, loved adventure too. When Arlo was born, Augustin wrote travel journals about his favorite places for Arlo to use when he was hold enough to go exploring on his own. When Arlo reads about Paris and the one the French call La Dame de Fer, or Iron Lady, he decides it's time to strike out on his first adventure. He travels to France and, guided by Augustin's journal, discovers the joys of Paris: eating a flakey croissant at a cafÔe, visiting the Louvre, walking along the Seine and, of course, meeting the Iron Lady... But who is she?
