Luo Changhu led a group of folk brothers to form an anti-Japanese guerrilla, but because he did not understand the overall deployment of our party, he intercepted the Japanese army's delivery of secrets. Weapons and vehicles also affected our party's anti-Japanese actions. In order to make up for his mistakes and join the Chinese Communist Party as soon as possible, Luo Changhu began to assist Communist Party member Zhang Wanliang in assassinating Matsui, who was Japan's number one expert in weapons research. It was also this action that made Luo Changhu meet his love Lan Xiner. The two fought each other to assassinate the target, but failed again and paid an unimaginable price for it.

Although Luo Changhu finally completed the task and destroyed the Ding Project, he also encountered the encirclement and suppression of the Japanese army early on, and all the shadow fighters died..
