The film, using the years 1919-1927 and 1951 as its timeline, presents Li Dazhao's tireless efforts to save the nation and its people from multiple dimensions and in greater depth. With extraordinary courage to be a pioneer and shoulder moral responsibility, he actively spread Marxism, igniting the flame of hope for the Chinese proletarian revolution and becoming one of the important founders of the Communist Party of China. Furthermore, the film, based on the pioneering thought led by Li Dazhao, resonates with the values of contemporary youth, achieving a dialogue of faith that transcends a century.
