Adapted from a novel of the same title, this film depicts a young woman’s transformation from housewife to loyal Communist. This process is presented as “natural” – possessed of inherent logic rather than merely “incidental”. Hence, the film is really about Communist revolution that won over the hearts and minds of Chinese youth.
During the War of Resistance Against Japan, a CCP army unit guarding the southwest border follows what is ostensibly a trading caravan and discovers that these traders are actually smuggling arms and spy equipment to Chiang Kai-shek and his American allies.
