Chow Tin Yan is a child prodigy who can foresee one second into the future because his heartbeat briefly pauses at birth. He is coerced by his father into cheating at gambling, a fate that leaves him feeling useless when the foresight proves only marginally helpful at the tables.
Years later, as an adult, Chow Tin Yan falls into a gambling spiral to fund surgery for his hearing-impaired son. He works at a pub, but debt collectors soon close in. To dodge their attacks, Chow leans on his rare gift, deftly sidestepping punches and sending rivals into confused tumbles. It’s this display of talent that catches the eye of a boxer and gym heir, Yip Chi-Shun, who invites him to become a sparring partner.
After a violent altercation costs him his pub job, Chow agrees to join the boxing world and begins training the next day. Yet his laziness and quick exhaustion raise doubts in Yiu Lin Min-Chen, Yip’s cousin and the gym’s yoga instructor, about his long-term usefulness. The situation shifts when Chow’s son Chi Leung accompanies him to the gym, rekindling Chow’s resolve.
Open championship fever arrives, but Yip Chi-Shun must step out because of asthma, leaving the gym short on excitement. The crowd and even the opponent feel the gap, and Yip asks Chow to stand in as the gym’s representative. Though Chow is a novice with merely amateur moves, his one-second foresight helps him dodge most blows and land a decisive strike, securing a surprising victory. This win spurs Chow to commit fully to boxing at the gym, pushing through grueling training with renewed energy.
As his skill grows, Chow Tin Yan climbs through the preliminaries and finally faces a formidable rival, Sung Ngo Yeung, in the finals. Sung’s brutal pace tests Chow as he dodges relentless assaults and even a surprise head punch. Suspicious of Chow’s uncanny efficiency, Sung investigates and uncovers his one-second foresight, filing a complaint with the boxing association that ultimately leads to Chow’s disqualification under the official rules on body standards.
Meanwhile, a champion named Joe finds himself financially stranded after accidentally killing an opponent. Joe’s coach seeks Chow’s gimmick-like foresight to attract new investments, hoping for a flashy exhibition match. The clash intensifies when Sung confronts Chow that night, accusing him of stealing a chance to fight Joe and of winning through supernatural luck rather than hard work. In the chaos, Chi Leung is frightened and bolts into the street; Chow tries to save him and is struck by a van, losing his foreseeing ability in the accident.
Sung apologizes, and with Chi Leung’s encouragement, Chow resolves to press on and fight Joe. At the start, Chow struggles, and Joe’s disdain grows as he seems to be outmatched. Yet Chow’s stamina carries him through a brutal ten-round battle, where both fighters sustain injuries and push toward the final bell. Through sheer grit, Chow appears to regain a touch of his foresight, dodging Joe’s last blows and clinging to life as the bout nears its end. In a moment of mutual respect, Joe rushes to steady Chow as the crowd roars. Although Chow loses on points, he finishes the night celebrated by his son and by the friends he’s made along the way.
