In 1925 Colonel P. H. Fawcett embarked on a journey into a dangerous and largely unexplored region of Brazil in search of a Lost World and was never seen again. Fleming's interest in Fawcett's disappearance leads to him answering an advertisement to join an expedition to explore the rivers of Brazil with the aim of ascertaining Fawcett's fate.
