一次偶會，森認識到雄心壯志、性格倔強的特技演員龍仔(劉俊謙飾)，聘請他成為助理，他從少志願成為成功的特技演員，這次必是發展事業的好機會。可是森處事嚴苛、個性吹毛求疵又專橫，跟威在片場發生多次衝突。龍慘成森和劇組之間的磨心。同時，森嘗試與關係疏離又即將出嫁的女兒Cherry(蔡思韵飾)和解，龍協助森改善與Cherry的溝通。

森除要面對自己的過去與威重修友好，又要讓導演的告別作最終動作場面得以完成，實在難以取得平衡。但團隊漸漸建立起默契，並拍出成績。接著在安排一場槍戰場面時，森的狂妄又發作，導致劇組演員被捕，森亦被解僱。

森徹夜未眠希望彌補過失，除避免當年悲劇重演及幫楚導完成最終動作場面，亦希望Cherry能以他為傲，他決心替龍上陣演出……

LEE Sam (TUNG Wai) 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 (Philip NG)- 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 (Terrance LAU), 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 (Cecilia CHOI). As Sam returns to the world he once dominated, he must confront his past, mend fences with Wai, and overcome their personal conflicts in order to deliver an epic final action spectacle for the director's swan song. However, in the midst of shooting a robbery heist, Sam’s shortsightedness endangers the public, and members of his crew are arrested, causing him to be fired.

As the pressure mounts and the stakes rise, Sam must decide what he's truly fighting for—reclaiming his former glory or reconnecting with the daughter he's taken for granted.
