 This is a literal retelling of the legend of La Llorona (the crying woman), present in many Latin American countries, a symbol of the native woman who betrayed her people by becoming the mistress of a conquistador, and a bad mother – in this case, a very bad mother, "a la Medea"– who kills the children she had with her Spanish conquistador lover.Taking parts from Carmen Toscano's stage play, the film is set in contemporary México, but flashbacks a few centuries to tell Llorona's sad story.She is now the nanny of the grandson of a descendant of those who punished her, and plans to kill their Child.
