Sull'orlo dell'abisso

Anna Ripley is an American journalist who arrived in Manaus to interview Mister No! But he ends up getting into the same trouble Jerry gets involved in, when our pilot agrees to take a cargo ship over the jungle. Its owner, Alejandro Cortenez, wants to get rid of a hot load and does not hesitate to sabotage the plane so that it crashes into uncharted territory. Saved from the plane crash, Mister No and Anna Ripley must now cross uncharted territory to return to "civilization". There, however, live the Makú, brave Indians for whom every white man is an enemy. Esse-Esse and Jesús, a young Indian who acts as their guide, arrive to help the two missing men.
