Posto-Avançado do Progresso plot
Two Portuguese colonial officials find themselves in a remote ivory trading post in Congo. In their white uniforms, they stand out as foreigners in the jungle and as "Mundele ghosts" in the eyes of the natives. They should get the business going again after the death of the former chief. Yet the recruited employees make too little effort to build up new reserves. While carefree Sant'Anna enjoys entertainment, alcohol, music and contact with the natives, his superior João de Mattos is soon stricken with malaria. The waiting and isolated existence in the jungle gradually increases mistrust and deception.
