In the 32nd year of the Republic of China, war broke out in Taihang. The Japanese invaders trampled the mountains and rivers with iron hoofs and devastated the land.
In troubled times, some people go to death with guns, and some wear armor to defend the country. However, Su Qinghe only relies on a three-stringed string instrument and his singing skills to walk in remote mountain villages. He is the only remaining folk rap musician in Taihang. He is unique in playing, speaking, and singing. He has been traveling around the countryside to perform for most of his life, just to live a stable life. But the fall of his family and country, the displacement of his people, and the tragic death of his beloved daughter by his rival made this old artist completely put aside the fireworks of the market and use string songs as a blade to enter the troubled times.
From then on, the two masters and apprentices traveled throughout the enemy-occupied hinterland, using the disguise of performing on the stage to sing, hiding secrets in the music of the strings, and conveying messages through the lyrics. The three-foot stage turned into a silent battlefield. A line of music concealed the opportunity to kill the enemy, and a string song moved the battle situation in Taihang.
They have no guns or armor, but they go deep into the tiger's den to eliminate traitors and detect spies; they are ordinary civilians, but they dare to fight against the Japanese invaders' cultural butcher knife with their cultural background. Faced with the pursuit of Japanese spies, cultural invasion, and the blockade of the entire territory, masters and apprentices weaved secret intelligence lines in desperate situations, and used folk arts to ignite hope behind enemy lines.
Wolf smoke covers the mountains and rivers, but the string songs refuse to be rejected.
Ordinary artists don't be bystanders in troubled times.
With a clear sound, we protect the local area and maintain the Chinese character.
Three feet and three strings are used as swords and guns, and a string song guards the Taihang; civilian artists lurk behind enemy lines, convey top-secret information with folk art, outsmart Matsumoto, Kuroteng, and Ono, and protect the immortality of the mountains and rivers!
