This effective drama about vengeance and its results is loosely based on practices in the Mexican boondocks where the law can be ignored when it comes to seeking revenge. The tale concerns two brothers who decide to avenge their father's death, as would be expected. But this ill-considered decision leads to a set of problems that continue to spiral downward until both brothers are in way above their heads. The difficulty with vengeance, they discover, is that it never ends.
