The film concludes with Valerian (Dane DeHaan) and Laureline (Cara Delevingne) successfully thwarting the plot of Commander Filitt (Clive Owen) to cover up the destruction of the peaceful alien race known as the Pearls. It is revealed that Filitt ordered the destruction of their planet, Mül, in order to hide evidence of the military’s unauthorized use of a converter—a powerful and rare creature capable of replicating anything it consumes.
Valerian and Laureline manage to expose Filitt’s actions and bring him to justice. During this process, they uncover the truth about the destruction of Mül and the hidden motivations behind the events that unfolded. They also discover that the Pearls managed to survive by using the converter to replicate a small portion of their planet and create a new home.
The climax involves a confrontation with Filitt in a holographic recreation of Mül. Valerian and Laureline, with the help of the Pearls, confront Filitt and force him to admit his guilt. The Pearls then extract the truth from Filitt’s memories and broadcast it to the entire Alpha space station, exposing the commander’s crimes.
In the aftermath, the Pearls are acknowledged and welcomed as peaceful members of the intergalactic community. Valerian and Laureline continue their adventures as space agents, and their relationship evolves into a more committed partnership. The film ends with them receiving a new mission, setting the stage for potential future adventures.
