In the twenty-sixth year of the Republic of China, the Japanese invaders trampled North China to pieces, and undercurrents surged in Jincheng (Lanzhou) in the northwest. Shi San'er, a raft guest at the Yellow River Ferry, is a man of brute strength and unruly temperament. He looks like a rough and tumble man, but he hides a sense of loyalty and unbridled passion.
There was a lot of traffic on the Zhongshan Bridge, the coal mines in Agan Town were dark, and the Chenghuang Temple was a mixed bag. In troubled times, Shi Saner was involved in the whirlpool of life and death among military commanders, spies, and local gangs. From a rough man struggling to make a living in the waves of the Yellow River, to a secret agent carrying the secret orders of his family and country, he struggled to survive amidst the swordsmanship and intrigues.
With the fireworks of Jincheng as the background and the raging waves of the Yellow River as the character, it depicts the struggle and perseverance of the little people in troubled times, a story of the Anti-Japanese War in the Northwest.
