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.
