Taxi 4 is the fourth installment of the ever-popular, Besson-produced French franchise. As the tale opens, a manically insane, hyperactive Belgian criminal, Le Belge, undergoes extradition to trial in Africa. En route, he temporarily lands in the Marseilles police department for a few hours where Emilien (Frédéric Diefenthal) works, and bamboozles him into believing that he's actually a Belgian embassy employee railroaded by the real crook, who is now at large. Emilien foolishly buys the story and sets Le Belge free, prompting an outrageous and explosive series of complications. But luckily enough for Emilien, his friend taxi-driver Daniel (Samy Naceri) who drove the criminal from the Police Station unaware of him being a criminal, comes to the rescue. When Emilien tells police commissioner Gilbert (Bernard Farcy) where he can retrieve the criminal he gets his old job back and the hunt for the criminal is on! This high-adrenaline, action-charged crime comedy was a box-office hit on the other side of the channel. It stars all of the original cast and a cameo from footballer Djibril Cissé.
