Lin Beiwang, an elite 21st-century sniper, dies on a mission and is reborn in a frozen 1958 mountain village as a disgraced gambler who offered his new bride, Yu Nianqiu, to settle his debts. Waking up in a destitute mud cottage faced with loan shark Wang Laowu's threats, Beiwang resolves to use his god-tier sniping skills to hunt in the wilderness and redeem himself.
With miraculous shots, he downs two roe deer with a single arrow and slays a giant moose, paying off his $200 debt. Impressing the village leader by shooting three sparrows in mid-air, he is appointed chief mountain guard. Fortifying his home, he repels a midnight wolf pack attack, rescues a mauled villager, and earns the community's deepest respect. Recognizing his true transformation, his grandfather bestows upon him a ancestral tiger-tooth necklace, officially passing down the hunter's legacy.
Determined to secure a better future for his family, Beiwang accepts a high-stakes hunting contract from a supply officer, battling a ferocious black bear with his rifle and grenade to harvest its prized bear bile. In return, he secures a city factory job for his mother and school enrollment for his sister. Meanwhile, the ruthless loan shark turned fugitive flees into the deep forest; Beiwang assists Police Chief Gao in capturing him, earning a special commission as the regional patrol captain.
Moving his family into a cozy city home, his mother thrives at work, his sister excels in school, and his beloved wife Yu Nianqiu becomes pregnant, completing his incredible journey from scumbag to legend.
