After her husband died in the line of duty, the martyr family subsidies for Zhou Lanying and her daughter were year after year exploited and embezzled by her mother-in-law Zhao Guihua and brother-in-law Chen Weimin. To buy a bicycle, the brother-in-law even forged her thumbprint to run up a tab, and her mother-in-law threatened her with death. Zhou Lanying no longer endures in silence, and with the help of the mining administration and the village organization, she clarifies the ownership of the subsidies, obtains the martyr settlement housing, and takes her daughter to move away from the village. Relying on work at the cafeteria, she becomes self-reliant, guards her daughter's growth, and completely breaks free from harassment, leading mother and daughter toward a gradually stable and peaceful life.
