Faro, la reine des eaux

Zanga (Fili Traoré) was born out of wedlock, making him a figure of scorn to the locals. Many years after being unceremoniously ejected from the village, Zanga returns wearing the façade of a successful engineer determined to usher his village into the modern era. When a young villager drowns in a nearby river, the locals draw the conclusion that river goddess Faro is enraged by Zanga's return. (rottentomatoes.com)
