Somewhere at the edge of known space is the Great Void. That inscrutable, shapeless, ever-changing place is where the expanding universe springs forth, where new planets and new life forms are created. It’s also, according to the gods of Hypsis, the place where Galaxity’s Earth was sent and is being kept prisoner. Valerian and Laureline begin a discreet investigation, but it doesn’t take long before they start finding obstacles in their path, placed by the rulers of Rubanis – and their mysterious master...

Valerian and Laureline take a break from adventuring and go on a cruise, but Valerian feels uncomfortable among the idle and the powerful. He’s not bored for long, though, because when a quartet of mercenaries board the cruise ship to kidnap the son of the Caliph of Iksaladam, they end up taking Laureline as well. With the almighty Caliph offering a massive reward for his son’s return, Valerian’s quest to rescue his girl is suddenly hindered by every bounty hunter in the galaxy...

The (false?) gods of Hypsis are once again interfering with Human history. Tired of their lower status among their peers, the trinity in charge of planet Earth opens communications with megacorporation Vivaxis at the end of the 20th century – an occurrence Valerian and Laureline’s allies report to the two ex-agents. But to what end did the Hypsians initiate such a contact? And who is the mysterious Sat who, from the depths of Point Central, also endeavours to meddle with Human affairs?

Running away with the unhappy heir to the galaxy’s biggest fortune, even if it’s because he wants it, is bound to cause some problems. On the lam with the Caliphette of Iksaladam, Valerian and Laureline are relentlessly pursued by the Quatuor Mortis, who are still after the enormous reward offered for the child’s safe return. Stranded among the Asteroids of Shimballil, they must evade the hunters, recover their ship, dodge profiteers and traitors ... and decide what to do with the little brat!

The expedition into the heart of the Great Void is launched, and Valerian and Laureline are on it. But in no time they’re already facing the mysterious force that threatens the entire galaxy: the Wolochs, gigantic sentient monoliths dead set on destroying any civilisation that might stand in the way of their domination. Our two Human agents can’t hope to stop the Order of the Stones by themselves, but fortunately, they still have allies...

"Valerian on the big screen ? I blame it all on Jean-Claude Mézières and Pierre Christin ! When I was ten, every week I'd read the adventures of Valerian in Pilote... And I have to confess that I was very much in love with Laureline, even though I quite liked Valerian. It'd be great if the film could make as strong and long-lasting an impression on its viewers." Luc Besson (from his interview with J. C. Mézières and P Christin) Born out of the Wild imagination of Pierre Christin and Jean-Claude Mézières, the characters of Valerian and Laureline first appeared in the pages of Pilote in 1967. Through its creativity and daring, the series quickly became the definitive reference for all readers of science-fiction bandes dessinées.
