It's vacation time for Det. James Carter (Chris Tucker -Jackie Brown, , The Fifth Element,) and he finds himself alongside Det. Lee (Jackie Chan The Forbidden Kingdom, , Shanghai Noon,) in Hong Kong wishing for more excitement. While Carter wants to party and meet the ladies, Lee is out to track down a Triad gang lord who may be responsible for killing two men at the American Embassy. Things get complicated as the pair stumble onto a counterfeiting plot by L.A. crime boss Steven Reign (Alan King -Casino, , Second Final Warning,) and Triad Ricky Tan (Golden Globe nominee John Lone The Last Emperor, , Year of the Dragon,), an ex-cop who played a mysterious part in the death of Det. Lee's father. Throw in a power struggle between Tan and the gorgeous but dangerous Hu Li (Golden Globe nominee Ziyi Zhang Crouching Tiger, Hidden Dragon, , Hero,) and the boys are soon up to their necks in fist fights and life-threatening situations.
