Tough Heart.

A patriot risked his death to assassinate a Japanese staff officer, hiding the secret information of the Japanese army's military operations in Shanghai in the "Centennial Tai Sui", and the Zhang family father and daughter secretly sent the "Hundred Years Tai Sui" to Shanghai. When they arrived in Shanghai, the father and daughter of the Zhang family died mysteriously, and Qin Taisui, an apprentice in the theater class, was inadvertently involved in this murder case, and the "Hundred Years Taisui" fell into the hands of Shanghai gangster Zhuo Yifan and was auctioned at a high price. At the same time, Qin Taisui, who wanted to clear his grievances, began to investigate the truth of the matter, joined forces with the patriotic anti-Japanese secret organization, and fought fiercely with the Japanese secret agencies to recapture the secret military intelligence, and finally walked towards the bright road through the baptism of blood and fire.
