Sam Hannah had been one of the ace flyers on the Western Front. In the 1930's he was down to pushing ancient planes over the worst jungles in the world.

Mallory was a flyer too. One of the new generation who would rather fly anything than not fly at all. Mallory needed a job and Hannah needed a partner.

Two men in ancient planes up against the savage Huna Indians on Brazil's Rio Das Mortes, the River of Death.
