In 1982, factory worker Chen Jianguo is reborn on the day his senior colleague, Zhao Desheng, gives him a pair of so-called good-luck-swapping gloves. In his previous life, wearing them brought him one accident after another, leaving his right hand crippled, while Zhao stole his technical achievements. This time, he passes the gloves to Zhou Wanshan, a crippled scrap collector, and discovers that the supposed luck-swapping trick actually allows Zhao Desheng to exchange his fortune with whoever wears them. As Zhao repeatedly steals food, frames others, breaks into lockers to steal notebooks, and sabotages equipment, Chen exposes his schemes one by one with the help of Zhou Wanshan, Gu Shouyi, Liang Xiaochuan, and others. He protects his technical achievements and uncovers hidden equipment hazards. In the end, Zhao Desheng is sentenced and fired, Chen Jianguo is transferred to the technical department, Zhou Wanshan reunites with his son, and everyone builds a better life with their own hands.
