Having lost everything, Paul Atreides seeks support from the population of Arrakis - the Fremen. He needs to learn their customs and understand how to survive on the desert planet, inhabited by giant worms and a resource called "spice". Only then can he put an end to the rule of the Harkonnens and transform Dune. But in his visions, Paul sees only a terrifying future: victory over the Great House of Baron Vladimir will bring about a Holy War in the name of the Atreides, which will affect the entire universe. Paul wants to prevent the inevitable, intending to complete the spiritual transformation into the prophet Muad'Dib from local legends. Some see in him the Messiah, awaited by many of the desert people, while others look at him with suspicion. Young Atreides is not very happy with this role, but gladly takes on the name Muad'Dib after several difficult trials. Now he must choose his own path and stop all the horrors of the impending war. He also needs to improve his relationship with Chani, a strong and determined girl from the Fremen people. The film is a continuation of the film "Dune", the plot of which is based on the second half of the eponymous science fiction novel by Frank Herbert.
