Valerian Movie Plot
In the 28th century, special operatives Valerian (Dane DeHaan) and Laureline work together to maintain order throughout the human territories. Under assignment from the minister of defense, the duo embarks on a mission to Alpha, an ever-expanding metropolis where diverse species gather to share knowledge and culture. When a dark force threatens the peaceful city, Valerian and Laureline must race against time to identify the menace that also jeopardizes the future of the universe.
Valerian and Laureline are special agents of the human police forces.
In a dream, Valerian sees a planet where a low-tech humanoid race lives peacefully in a tropical paradise. They fish for energy-containing pearls and use certain animals to duplicate them. As this idyll is destroyed by spaceship debris crashing onto the planet, Valerian wakes up.
He and Laureline are on a mission to retrieve one of the rare animals from his dream, called a “converter”, from a black market dealer. Early in the mission, Valerian asks Laureline to marry him, but she brushes him off, knowing of his many affairs with female colleagues. Valerian interrupts a meeting of the dealer with two prospective customers for the converter, both looking like the humanoids from his dream. He and Laureline obtain the converter, and he surreptitiously steals one of the pearls that had been given in payment to the dealer.
They return to Alpha, where they are told by Commander Filitt that part of the station has been infected by an unknown force, rendering it highly toxic, that troops sent into the area have not returned, and that the infection is spreading. Laureline and Valerian are assigned to protect the commander. He asks Laureline for the converter, but she refuses.
While he briefs an assembly about the infection, they are ambushed by the humanoids, who incapacitate all participants and kidnap him. Valerian frees himself and the others and chases the kidnappers, who head for the infected area. Valerian loses control of his vehicle and Laureline loses contact with him.
She goes searching for him and finds him unconscious at the edge of the infected area. She wakes him up but is kidnapped by a group of primitive humanoids. Valerian infiltrates the residential sector of the group with the help of shapeshifter Bubble. He saves Laureline and they escape, but Bubble is killed in the fighting.
Valerian and Laureline venture further into the infected area, realizing that it is not actually radioactive, and reach a large, shielded hall where they find a large group of humanoids holding Commander Filitt. Their leader explains that his people were living peacefully on the planet Mül when two technologically advanced races, one of them human, fought a war in space above Mül. The human commander ordered the firing of a doomsday weapon, over the protests of his subordinates. That weapon destroyed the enemy, but also Mül. A small group of survivors sheltered in a crashed spaceship and managed to repair it, learning much about technology and the history of other races in the process. They eventually came to Alpha, where they assimilated more knowledge and constructed a spaceship that could recreate a planet like Mül. The hall they are standing in is that spaceship, and they have kidnapped Filitt in order to obtain the converter and the pearl they need to launch the ship.
When Valerian and Laureline interrogate Filitt, they learn of his role in the destruction of Mül and the extent of his coverup.
Valerian has the pearl he took during the black market deal, and Laureline has the converter. Valerian gives them his pearl, but Laureline has to talk him into giving them the converter, since their mission was retrieve it for their government.
While the spacecraft is prepared for flight, Filitt’s pre-programmed robot soldiers attack the government rescue mission that has come for them. Valerian, Laureline, and government officials and soldiers thwart the attack. The spacecraft departs with them onboard, while Filitt is arrested by the police. In a final scene Valerian and Laureline confess their love.
