In search of a genuine news scoop, entertainment reporter Mui (played by Kelly Chen) heads to London to report on an antique auction, aiming to track down the elusive Nine-Tailed Fox (portrayed by Tony Leung Ka Fai), a notorious art thief who has managed to avoid capture for many years. The Fox, known for his cunning and charm, decides to enlist Mui as his accomplice for his next heist, targeting a collection of Tang Dynasty pottery horses. Unbeknownst to the Fox, Mui is secretly collaborating with Cheung Ho (Ekin Cheng), a Hong Kong detective who has been fixated on apprehending the Fox ever since he slipped through his fingers years ago. This leads to a thrilling chase filled with unexpected twists, taking the trio from London to Prague.
