1949, a medical station in the heart of the Amazon rainforest. One day, a severely injured photographer washes up there, managing to report on a disturbing encounter just before he dies. The head of the station is left with only an undeveloped film to unravel this mystery. As soon as he has prints made in the city, the British Secret Service arrives in Manaus, and a group of German immigrants also shows great interest in the mysterious image. It's no wonder, as it suggests that an alien being is among the Indians in the jungle. After several epic adventures in space and a detour to Africa, Leo now chooses his home country of Brazil for the setting of one of his imaginative and thrilling stories for the first time. One can be sure of that.
