The South-East province of the Democratic Republic of Congo is one of the richest regions in the world in mineral resources. Why does the population of Katanga continue to live below the poverty line? Conceived as a political-economic thriller, this investigation by Belgian documentary filmmaker Thierry Michel attempts to understand how multinationals take control of the region's wealth. National officials in the Democratic Republic of Congo have ceded all Katangese land to the mining industry, to the detriment of agriculture. Thanks to trafficking to which the authorities turn a blind eye, the minerals are largely fraudulently leaving the country, destined in particular for China.
