Since the September 18th Incident, the Japanese invaders have never stopped their actions of encroaching on the land of China, but have extended their greedy claws to the hinterland of China. In 1932, the "January 28th" Songhu Battle broke out. The soldiers of the 19th Route Army fought bloody battles with a common hatred of the enemy. Their iron will and spirit deeply infected the people of Shanghai, including Zhou Wen (played by Wen Zhang), a rich boy. This upright and patriotic young man did not hesitate to resist the oppression of the Japanese on his own. After that, he broke with his family and entered the Central Military Academy under the pseudonym Zhou Weiguo. His excellent qualities and outstanding qualifications were appreciated by instructors and senior officials, and he was given the opportunity to continue his studies. Zhou Weiguo, who returned from his studies, threw himself into the War of Resistance against Japan with full enthusiasm. In the long years that followed, he would face countless difficult tests that ordinary people could hardly imagine... This film is adapted from the online novel "Special Warfare Pioneer".
