The story revolves around Daniel (Sami Nasseri), a pizza deliveryman who turned into a taxi driver, and Emilian (Frédéric DiFondo), a handsome but confused Marseille policeman. Daniel has superb driving skills. The taxi he drives has been specially modified and often speeds on the road. With the help of the modified taxi, he has helped the Marseille policeman, who is always making mistakes, to solve cases many times. Emilian is Daniel's good friend. He is handsome and sometimes a little confused and always does stupid things. Daniel is often needed to help him clean up the mess. Emilian and his Marseille policemen have received an important task: to guard the Belgian terrorist leader who is being escorted across the border for 24 hours. The Marseille police chief, Guibert, who is a master but not powerful, deployed a "dragnet", but he almost lost the prisoner before leaving the airport, which made the military furious; and Emilian's beautiful and hot girlfriend Beta received another undercover mission, and the two had to separate their just-started vacation... In order to rescue their leader, the terrorist organization carefully designed a series of attacks in Marseille. And the French government seemed to be prepared for this. A carefully planned serial conspiracy began, the mantis stalked the cicada, and the oriole was behind. But who is the oriole?
