When a cyber-criminal gang disappears with billions, evading capture by outsmarting the Police's formidable "Sky Eye" surveillance system, they desperately enlist the help of a legend. Wong Tak-Chung (Jackie Chan), a retired tracking expert, mentors a rookie officer and rebuilds an elite surveillance unit. Their mission: to track down the elusive "Wolf King," Fu Longsheng (Leung Ka Fai Tony), the mastermind behind the heist. As the police close in, the thieves spring a trap of their own. Brains clash, loyalties are tested, and the ultimate cat-and-mouse game is about to begin. From award-winning writer-director Larry Yang (Ride On), Jackie Chan and Leung Ka-Fai Tony reunite for the first time in twenty years. The Shadow's Edge references elements of Jackie Chan's Police Story character while offering a contemporary take on the "veteran cop" archetype.
