Plot Summary:
It is the year 10,191, various planets inhabited by mankind are ruled by a feudatory Padishah Emporer known as Shaddam IV (José Ferrer). Amongst these vassals are the Baron Vladimir Harkonnen (Kenneth McMillan) and his enemy, Duke Leto Atreides (Jürgen Prochnow), whom the emperor has come to fear as a possible rival. In order to rid himself of this potential threat, the emperor conspires with the Harkonnens. He grants the Atreides control of the planet Arrakis, the sole source of the Spice, a mysterious substance that allows the navigators of the Guild, a powerful organization that monopolizes interstellar travel, to fold space and thereby travel from world to world. Some time after the Atreides' arrival on Arrakis, the Harkonnens, aided by the emperor's own soldiers, attack and destroy them. The duke's son, Paul (Kyle MacLachlan), survives and escapes to live with indigenous tribes of people who were once thought not to exist. Rallying these rough nomadic tribes around him, Paul begins his journey to create peace and bring a new universal order.
