After a young man is killed in an unexplored subterranean cavern and his girlfriend driven mad by something she saw there, a track found at the scene cannot be identified with any known animal and thus a scientific expedition is launched to find out just what it is that is living there.

The building of a railroad under tough conditions from searing heat to freezing cold in the Sonora desert provokes clashes of passion and struggles between the engineers and the workers at the campsite. The workers also contend with sudden dust storms that are called the 'black wind'. Based on true events.

Revenge, love and hate will at the end bring out the truth and everyone will get what he deserves.

1946 film by Miguel M. Delgado

A useless and bloody vendetta has been going on for ages between two families in this Mexican village. Men, sons, have killed each other for generations, for a so-called conception of honor in a revenge that never ends since it is also triggered by people of the village. Now, today, there are only two sons left, one in each family. One has become a doctor in the big city and his culture is modern. The other last one - of the other family - hasn't left the village and is waiting for the doctor to come "home" as he plans to kill him, to settle this war on this matter of honor once and for all. And the people of the village want blood.
