Set in China's oil fields, the film follows enthusiastic young workers pushing forward the nation’s modernization. Liu Sicheng (Liu Ye), a top performer, idolizes oil hero Wang Jinxi (Wu Gang) and is proud of his father, Liu Wenrui (Zhang Duo), who once worked alongside him. Meanwhile, Zhao Yilin (Huang Bo), a cynical youth, questions his father's legacy. Flashbacks reveal the hardship faced by Wang and his team when they arrived in barren Daqing, working five days straight to help China shed its "oil-poor" label. Wang’s iconic moment—jumping into cement despite an injury—becomes legendary.
