The film takes place several years after the events of Rush Hour 2. Lee (Jackie Chan) and Carter (Chris Tucker) are once again teaming up to solve a new case. This time, they're in Paris to stop a French gangster named Arthur Bishop (John Travolta) from stealing a shipment of diamonds.
The movie follows Chief Inspector Lee (Jackie Chan) and James Carter (Chris Tucker) as they travel to Paris to help a French diplomat, who has information on a Triad crime lord. However, they soon discover that the diplomat has been killed, and they must find the killer and the stolen evidence.
The comedy, on the other hand, is provided by the odd-couple dynamic between Lee and Carter. Chris Tucker's antics are as over-the-top as ever, while Jackie Chan's dry wit provides a perfect counterbalance.
