He was ordered to return to his hometown from the front line of suppressing * * *, supervise the pursuit of the independent division of the Red Army in eastern Guizhou, and began to expand the army and reorganize the local garrison. Because of his sympathy for the Red Army wounded and the promotion of his lover Huang, he took risks to facilitate the evacuation of the Red Army wounded, but was denounced by his grandson Sun, who knew the news, which led to the complete failure of the evacuation of the Red Army wounded and the commercialization of the family.

Zhang Mingtang, in a dilemma, was taken in by the owner of Taohuazhai who admired him. He decided to go down the mountain to avenge his family.

Sun was once a master who accomplished nothing. Driven by emotion and family feud, he decided to join the army and become the battalion commander of the local garrison. As a result, it launched a feud with Zhang Mingtang for many years.

Although the Red Army failed to evacuate, the red seeds did not perish. Under the leadership of Xia Xue, the instructor of the Red Army, the Party organization was restored and the revolutionary forces were reunited. After the full-scale outbreak of War of Resistance against Japanese Aggression, they publicized anti-Japanese and organized people to support the front.

Huang was brutally killed by Japanese spies and bandits when he organized the transportation of anti-Japanese war materials. Sun Bairu was frightened by his wife's heroic sacrifice. He tried his best to destroy the bandits who took refuge in the Japanese army to ensure the safety of the anti-Japanese materials transportation road. With Xia Xue's help and persuasion, Sun and He put aside their differences and came together on major issues of national survival.

Together with Sun, he led his hometown children to the battlefield without hesitation and participated in the battle of Xuefeng Mountain. They held their ground in a bitter and desperate struggle. When reinforcements arrived, they ran out of ammunition. Together, they jumped off the cliff facing their hometown, sacrificed their lives for the victory of the battle of Xuefeng Mountain, and also sang a heroic hymn of young people's belief in progress and selfless dedication for the country.
