Three old geezers, activists, and lifelong friends reunite at the funeral of the wife of one of them, Antoine, who finds out about a long ago liaison between his dearly departed and the reviled billionaire who owns the factory they all worked in. Livid, Antoine jumps in his car and heads for Italy with revenge on his mind, his two buddies and his pregnant granddaughter following close behind. A chance to reminisce about the past, to fantasize about sticking it to the man, to discuss what’s wrong with the world, to bridge the generation gap, to forgive and forget and settle scores. A wickedly funny geriatric road trip!

An apparently simple mission – apprehending a speculator-droid – turns into a race against time when the Shingouz drop in uninvited mid-arrest, begging Valerian and Laureline for protection against someone who means to kill them. To the agents’ surprise, it’s an old friend who soon pops up in hot pursuit, guns blazing. The ensuing shoot-out does little to simplify an already complicated situation: our heroes’ favourite information brokers have managed to … lose Earth in a card game!
