LEE Sam was the undisputed king of stunt choreography during the golden era of Hong Kong action cinema in the 80s. After a devastating stunt accident, Sam steps away from the industry for 30 years. However, his old friend, a veteran director, has now persuaded Sam to work as the stunt choreographer on what will be the director's last film. The only catch is that his film stars Wai - Sam's former stunt crew member who has since become a famous action star in his own right. Sam and Wai have a contentious history, with Sam's infamously overbearing and demanding personality clashing with Wai's own ego and ambition. By chance, Sam crosses paths with a young, ambitious stuntman named LEE Sai Long , who sees this as an opportunity to advance his career. Long is caught between Sam and his former protégé turned rival. At the same time, Long helps Sam to reconcile with his estranged daughter, Cherry.
