La Llorona

The blood of immigrant children has so overwhelmed the rivers of South and Central America that the cries of the innocent have awakened the dark powers of the ancient warrior, La Llorona. 

"La Llorona" is an art-house horror short film that employs the Mexican myth of La Llorona to create an ancient killer whose power to kill has grown because of the killing and trafficking of innocent immigrant children.
