The documentary is about a Czech researcher, Tomáš Ryška, who goes to the Thai and Laotian mountains in order to search and document the causes of wrongdoing and violence done to the indigenous peoples and their children by Christian missionaries.

According to the film, the missionaries' altruistic intentions of converting these indigenous people to Christianity hide the human rights violations of land theft, forced relocation, cultural genocide and imposition of power with a racist view on their society.

Using an assumed identity, Ryška investigates the living conditions of Akha children in Chiang Rai area missions and orphanages.

One missionary, "Vern", discusses how the goal of educating Akha children was to ultimately return them to their home villages to proselytize among their own people.

Ryška suggests that Christianity is the true religion of fear and explains in detail on how missionaries stir conflict in villages, buy land, and control converts.

However, the Laotian government has invited Western NGOs into the country as part of a poverty reduction campaign concerning ethnic minorities such as the Akha.

The program involves relocating the Akha to lowland villages (where they deal with unscrupulous Lao customers) and road construction in their traditional lands.

Ryška alludes to the 2003 war on drugs in neighboring Thailand, which killed and injured many Akha whose livelihoods are dependent on opium cultivation.

The Akha villagers allege that workers from the NGOs Action Against Hunger (ACF) and Norwegian Church Aid (NCA) are guilty of rape.

It also notes that the NCA changed its policies after an internal investigation confirms Ryška's findings and that other indigenous peoples around the world are suffering fates similar to that of the Akha.
