Welcome to the Jungle (2007) on Netflix

Plot summary

Two couples, Colby and Mandi and Mikey and Bijou, travel from Fiji into the wilderness of southwestern New Guinea. They mean to find Michael Rockefeller, son of New York Governor Nelson Rockefeller, who vanished there in 1961, and sell an interview with him to tabloid newspapers for a million dollars. Armed criminals and border guards put them in danger on the way, and a local community shows them evidence that suggests Rockefeller may still be alive. The group pushes deeper into the jungle.
