In the cold winter of 1976, three-and-a-half-year-old Zhao Suisui was abandoned in the snow by her biological mother, Lu Mei, as a broom star. Her uncle Lu Zheng, who had a reputation for being fierce, ignored criticism and picked her up back to her dilapidated thatched hut. The koi carp brings good luck every year, and wild animals and precious medicinal materials frequently show up. The uncle and nephew earn money, food and cloth by traveling to the mountains to harvest, and life gradually improves. Lu Mei, his grandmother Wang Pozi and other top relatives were jealous and came to the house many times to steal property and even follow him into the mountains to covet the treasures. Lu Zheng used force to protect Sui Sui, and with the help of Gu Jianguo, the old party secretary, he thwarted his relatives' schemes time and time again.
