The release of this drama about Colonel Fawcett, a well-known explorer of South America at the turn of the 20th century, promises to become a major event in cinema. Fawcett intends to uncover a lost city in central Brazil. Before leaving, he requested that a search party not be organized for his group if it did not return by the designated date. Fawcett never returned, and numerous attempts to learn of the fate of his expedition came to nothing.
