We are in Mexico towards the end of the 19th century. The war against the Indians has long since ended after a long succession of bloody battles. Most of the red tribes have surrendered to the will of the whites who begin in the new land of America the construction for a new civilization of peace and work, guaranteed by the richness of the soil and the power of their wits. But the peace won by the pioneers in the West was not enough to appease the ferocious Red Indians and some of the defeated tribes who rebelled against the will of the victors, in the shelter of the rocky mountains of the West, lead a nomadic life, devastating and killing, led by ferocity and by an insatiable desire for revenge. Among these tribes the most terrible is the one led by Nevecka, cruel and beautiful woman whom the whites have nicknamed "The Black Venus".
