The Secrets of Atlantis: The Sacred Legacy

In the beautiful thirties, a young aeronautical engineer, Howard Brooks, is attacked on board of the Hildenburg, a zeppelin he himself helped to construct, in a trip back to New York after a conference in Germany. Disoriented, he soon discovers the cause after the mysterious attack: an organized group is behind a mystic artifact of which Howard is heir; an object that might be essential to locate the legendary lost continent of Atlantis.
