Lao Pei (played by Wu Gang) and his family have been guarding the desert for ten years in order to defend the gold mine he discovered. For ten years, there has been a financier who wants to buy the mine, but Lao Pei has been reluctant to agree. The financier is furious and sends a killer to "solve" Lao Pei. At the same time, the information about Lao Pei and the gold mine spreads like wildfire, causing people from all walks of life to rush to the desert. The three real estate speculators: Xifeng (played by Ying Caier), Liu Tiao and Ba Tong are the first to attack. They use the mahjong game to try to disintegrate the mutual trust between Lao Pei and his wife Xiu Sao (played by Yue Xiuqing), but are driven out by Lao Pei, who is more skilled. Director Deng Ge and the crew, as well as Dr. Zhang Qing, a geologist, and his sickly girlfriend Yueyue, arrive one after another. The two groups of people use beauty tricks and professional geological knowledge to try to get solid evidence of gold in Lao Pei's mine. Lao Pei, his wife and son Xiao Pei have experienced a series of challenges to defend the gold mine to the end for Lao Pei's dream.
