Valerian (Dane DeHaan) and Laureline (Cara Delevingne) are special agents of the government of human territories, responsible for maintaining order throughout the universe. Valerian wants more than a professional relationship with his partner and makes that clear. But her extensive history with women added to Laureline’s more traditional values led her to reject a novel.
Following orders from his commander (Clive Owen, from The Specialists), Valerian and Laureline embark on a mission to the intergalactic city Alpha, a constantly expanding metropolis made up of thousands of different species from all four corners of the universe. Alpha’s 17 million people converged on time and the desire to bring together talents, technology and resources for the betterment of all. Unfortunately, not everyone at Alpha has the same goals. In fact, invisible forces are operating in the city, putting the human race in great danger.
