In 1991, heavy rain poured continuously over the Daliang Mountains. Young Lin Zichuan struggled to survive with his critically ill sister. However, village bully Guo Daman led a group to his doorstep, attempting to forcibly seize his family's leased forest on the pretext of unpaid taxes. Driven into a corner, Lin Zichuan risked entering the forbidden mountain to gather medicinal herbs and accidentally saved a one-eared, scabby black pig trapped in a wire snare. He even sacrificed his father's only remaining keepsake to spare the pig's life. Little did he expect that this pig, viewed by others as a bringer of bad luck, would lead him to sky-priced black gold deeply buried underground. The envious village bully pressed on step by step to steal his source of wealth, as a battle between greed and conscience quietly unfolded in the mist-shrouded deep mountains.
