The legend of Er+-¬ndira tells of a brave young Indian woman who took up arms against the Spanish conquistadors during their 16th century invasion of Latin America. Though about to be married, she stands up to the social conventions of her people, the Purepecha, so that she may fight the invading Spaniards. She steals a horse from the Spanish, learns to ride it and then uses her skill against her conquerors. In doing so, she became a potent icon of strength and rebellion for indigenous Mexican cultures. The story was taken from a pre-Colombian codex that reveals the history of the Purepecha people, the soundtrack was based on authentic music and sounds, and the film was shot in the native Purepecha language.
