In Jackie Chan's POLICE STORY, Kevin (Chan), a heroic cop with the Hong Kong Police Department, is assigned to guard a key witness in the trial of a mobster he single-handedly captured. But the tables are turned when Kevin is duped by the comely witness. The drug boss is then released for lack of evidence, and Kevin is framed for murder. This entertaining action film, also starring Maggie Cheung and Brigitte Lin, spawned a successful franchise and is widely considered to be one of Chan's best movies.
