Lu Xuezhi, a rural girl, left her hometown and went to settle in her sister's house in Daxinganling. After graduating from secondary school in forestry, she began her career as a lumberjack. In the vast forest, wild beasts are infested, and the logging labor is very hard. But the stubborn Lu Xuezhi fell in love with the cut, and was selected as a young commando. During the labor, Xuezhi fell in love with the simple lumberjack roots, but his brother-in-law, Lu Minzi, strongly opposed and obstructed him. Her brother-in-law wanted to marry her to a powerful civil affairs cadre, but Yukizhi resolutely refused. Since then, Xuezhi has encountered various difficulties such as not being able to get a regular job, and not being able to issue a certificate for marriage. In order to complete the marriage proposal, Fang Genzhu's mother and son tried to intercede with Lu Minzi with money and goods, but they were refused. Xuezhi moved out of her sister's house in anger, and she was so disappointed by Genzhu's cowardice that she decided to fight to the death and committed suicide by jumping into the river. Fortunately, he was found and rescued by Jiang Youlin, secretary of the Youth League Committee of the Forestry Bureau. When Jiang Youlin learned about the situation, he went to Lu Minzi to comment on the situation, but was ridiculed and criticized by some people. Lu Minzi was even more full of nonsense, slandering Xue Zhi, making Xue Zhi embarrassed. The arrogance of her brother-in-law and the weakness of her fiancé make Yuki-eda feel cornered and decide to return to her hometown. Jiang Youlin explained to her the meaning of life and inspired her fighting spirit, while at the same time persevering in running around for Lu Xuezhi to win the freedom of marriage. On the eve of her marriage, Lu Xuezhi felt a spiritual distance between herself and Genzhu. She was conflicted and painful, but still decided to make a promise. Feeling his cowardice, he did not want to be affected by the snow branches, so he finally took part and joined the ranks of extinguishing the wildfires.
