A gang of thieves calling themselves the Santa Claus Gang are wreaking havoc, and the police can't keep up. Police Captain Gilbert is distracted by a Chinese reporter writing a story on his squad, detective Emilien's wife has just announced that she's pregnant, and taxi driver Daniel is in the midst of a relationship crisis. After a string of mistakes in which the thieves outsmart the police time and time again with a reporter there to record it all, Daniel and his super-taxi pitch in.
