David Zheng was assassinated at his home. He was the owner of the Dawan Hydropower Station under construction. Who was the murderer? Love killing? Vendetta? In the era of "power shortage" across the country, hydropower development has become a hot spot for various funds to pursue profits. However, the Dawan Hydropower Station has become a hot potato due to a broken capital chain. His lover left him. Wang Xiufen, the contractor for the power station construction, was deeply involved. He lost the company and his family for him, and his partner Du Fei was incompatible with him. Du Fei left David Zheng aside and used Lin Lanfang's rosy public relations. The new Dawan Power Station became a "government project" and was rolled out in full swing. Soon, a corruption case surrounding the construction of the power station was exposed, and a large number of officials, including the deputy secretary of the municipal party committee, acting mayor, and secretary of the county party committee, were investigated and punished. Dawan Power Station returned to David Zheng. Chi Xiaoqin, a former college classmate of David Zheng, brought money to invest in the Dawan Power Station. At the same time, he started to invest emotionally in David Zheng, and a "love encounter" broke out between the three of them. It turns out that David Zheng, an educated youth in Dawan, had an unforgettable brother-sister relationship with Wang Xiufen, a native of Dawan. David Zheng returned to his hometown with simple ideals to build a mountain village and build the Dawan Power Station. He received Wang Xiufen's full support. In order to build the Dawan Power Station, she chose to give up, burying her love deeply in her heart. David Zheng's twin brother Zheng Xiaowei has always been secretly in love with Chi Xiaoqin, and he always cares for her everywhere. After half a century of construction, the Dawan Power Station was finally built to generate electricity with the efforts of David Zheng, Chi Xiaoqin, Wang Xiufen and Zheng Xiaowei, fulfilling the long-cherished wish of two generations. Love for hometown, love for rivers, family affection, friendship, and love, all come together...
