Jose del Carmen Valenzuela, the Jackal of Nahueltoro, brutally killed a mother and her five children. Superstitious, he placed stones on their chests. In prison, he transforms, learns, and finds compassion before his execution for his crimes.

Miguel Littin made an indelible debut with this fiery, legendary work of wrongdoing and redemption. Captured with haunting cinematography by Hector Ríos, this serial-killer film not only rattles with extreme violence, but exposes the manifold hypocrisies at the heart of 1960s Chilean society.
