[4] A pair of explorers, Lewis Moon and Wolf, become stranded in Mãe de Deus (Portuguese: Mother of God), an outpost in the deep Brazilian Amazon River basin, after their plane runs out of fuel.

The commander cuts a deal with Moon: if he and his fellow mercenary would bomb the Niaruna village from the air and drive them away, they will be given enough fuel for their airplane and be allowed to leave.

They arrive in Mãe de Deus to meet fellow missionaries Leslie and Andy Huben, who live with a Niaruna helper.

In town, they meet a Catholic priest who wants to re-establish a mission to the Niarunas, as the former missionary was killed by them.

But upon seeing the community with his own eyes as well as a native American firing an arrow at the plane, Moon has second thoughts.

That night, after a discussion with Wolf, Quarrier and the priest, Moon takes a native drug and begins hallucinating.

Native Americans originally converted by the Catholics turn up, awaiting the arrival of the Niaruna.

Young Billy dies of blackwater fever (a serious complication of malaria), causing Hazel to lose her sanity.
