A young man is confined in a mental hospital. Through a flashback we see that he was traumatized as a child, when he and his family were circus performers: he saw his father cut off the arms of his mother, a religious fanatic and leader of the heretical church of Santa Sangre (“Holy Blood”), and then commit suicide. Back in the present, he escapes and rejoins his surviving and armless mother.

Shot in France, England, Switzerland and the United States, this documentary covers director Alejandro Jodorowsky (El Topo, Holy Mountain, Santa Sangre) and his 1974 Quixotic attempt to adapt the seminal sci-fi novel Dune into a feature film. After spending 2 years and millions of dollars, the massive undertaking eventually fell apart, but the artists Jodorowsky assembled for the legendary project continued to work together. This group of artists, or his “warriors” as Jodorowsky named them, went on to define modern sci-fi cinema with such films as Alien, Blade Runner, Star Wars and Total Recall.
