Demetrio Azunsolo arrives in a small remote village outside Mexico where his beloved half-brother, Ricardo Platas, used to live and run a tequila plantation, only to find out that the latter has just committed suicide, after being betrayed by a selfish, greedy woman.

Little by little, and thanks to the village inhabitants - who at first are hostile towards him but then become his friends - Demetrio puts together the pieces of the puzzle that led to the tragedy.
