The Cocaine Jungle examines the effectiveness of the United States' Plan Colombia, a multi-billion dollar investment of time and manpower to aid Colombia's elite anti-narcotic units -- the Junglas -- in the fight against cocaine production.

Paul Kenyon travels with the Junglas as they comb the rainforest with an informant who points out hidden cocaine laboratories -- a highly dangerous undertaking. The program also reveals how senior US soldiers have been accused of arms trafficking and cocaine smuggling themselves, exacerbating the very drug war they are there to sort out. And as entire villages flee the US coca spraying planes and intense fighting around cocaine producing areas, Colombia has amassed the second largest number of "internally displaced" people in the world. Is Plan Colombia really working at all?
