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.
