Joe D'amato's experience as a cinematographer made this a very effective Gialli.

Here he directs Klaus Kinski and gorgeous Ewa Aulin in this wild story of a man who uses an ancient Incan formula to raise the dead and uses it for his own series of revenge murders. Bizarre, surreal and at times incomprehensible, this D'Amato film (which he also scripted) is full of hypnotic scenes and strong scenes of violence.
