Treasure of the Amazon

Gringo (Stuart Whitman), an adventurer in the South American jungle, wants the diamonds buried deep in the Amazon, and he is not the only one hunting them. Klaus von Blantz (Donald Pleasence), a former Nazi, and a crowd of rivals are racing him to the same spot, while a priest (John Ireland) and Clark (Bradford Dillman) are caught up in the chase. René Cardona Jr. keeps the camera moving through the glare and grain, never letting the pace slacken.
