At the time, the people living in the Amazon Basin were rich due to the natural resource of latex.
The best rubber is produced in Acre, a region that, although inhabited by Brazilians, is theoretically part of the Republic of Bolivia.
The novel starts when Galvez falls from a window, running away from a lady's husband, and, accidentally, saves the life of Luiz Trucco, the consul of Bolivia.
He is rescued by the ship of Sir Henry, an English metaphysical scientist who thinks the Amazon Theatre is a spaceship, and Justine L'Amour and Blangis are Opera artists and part of the trouppe Les Comédiens Tropicales.
Some weeks later, he and Les Comédiens go to the Bolivian city of Puerto Alonso, Acre, in a ship, where Trucco and the neurotic consul of United States are traveling.
A graphic novel adaptation in Portuguese was made by Miguel Lalor (pencil/color) and Andrei Miralha (ink/color) in 2004, as a limited edition by the Government of Para/Brazil (Secult/PA).
