Out to stop a new gang disguised as Santa Claus, Emilien and Daniel must also handle major changes in their personal relationships.

Police inspector Emilien and his taxi-driver pal Daniel are back, this time on the tail of a group of Japanese yakuza.

To work off his tarnished driving record, a hip taxi driver must chauffeur a loser police inspector on the trail of German bank robbers.

Daniel, the driver of a very special taxi in Marseille, gets a famous soccer player to the stadium in time and later helps his clumsy police friend Émilien catch the dangerous Belgian after he escaped on Émilien's guard.
