In the year 10191, the film opens on the desert planet of Arrakis, also known as Dune, where the valuable spice melange is harvested. The spice is crucial for space travel and grants extended life and heightened mental abilities. The planet is harsh, with giant sandworms lurking beneath the surface. The Emperor of the Known Universe has decided to transfer control of Arrakis from the Harkonnens, a brutal ruling family, to House Atreides, led by Duke Leto Atreides, his concubine Lady Jessica, and their son Paul Atreides.

Duke Leto receives a message from the Emperor, informing him of the transfer of power. He is aware that this is a trap set by the Emperor and the Harkonnens, but he sees it as an opportunity to forge an alliance with the native Fremen, who are skilled fighters and know the desert well. Meanwhile, Paul has been experiencing strange dreams about Arrakis and a mysterious girl, which he shares with his mother, Jessica.
