In 1937, after the Great Japanese Empire launched its aggression against China, Bai Niansheng, Han Meiyu , Tang Siye and the Chinese Communist Party member Li Shaofei jointly defended the country in Tianjin.

The Japanese army began their invasion of China in 1937. Niansheng (Yang Yang) who was raised by an abbot is forced to come down from the mountains to take revenge for his master after he was murdered in the hands of the Wu Hu Clan. Along the way, he saves Han Meiyu (Zhang Jiani) from harm and an extraordinary relationship develops between the two. Tang Si Ye (Lian Yiming), the leader of the Loyalty Hall, and Li Shaofei (Niu Baojun), a member of the Communist party, chance upon mass killings launched by the Japanese to recover the formula for a biological weapon.—Sonja Pavkovic
