Children, your's father also killed the devil. Your father is not a traitor, but my father is undercover. Shi Daliang, an eight-way chef, claims to be a descendant of Shandong cuisine, but in fact he can only cook cauldron dishes. Later, undercover worked as a chef in the Japanese army and almost got into big trouble. The team won the battle that day, and he finally got the news of his long-lost son, Shi Laifeng. Originally, he asked for leave to find his son, but he received an urgent task from the head of the team, Yu Xiaojiang, to let him penetrate the Japanese army, find out the identity and conspiracy of the mysterious enemy, and sent his first love, Comrade Li Erqin, to contact him on a single line. Shi Daliao mistakenly entered a Japanese military camp undercover as a cook, but he didn't know that he was my brother, and the restaurant owner Lao Qiu who escaped from the Japanese encirclement with him that day was the mysterious figure Qiu of the Japanese army. Shi Daliao and Li Erqin really put on a show as husband and wife. They covered each other, fought against the enemy, saw through each other's plots again and again, and intercepted key information for the Eighth Route Army. His son Shi Laifeng was brought into the team by Yu Xiaojiang. During the operation, he met Shi Daniao many times, but he didn't know his identity. Shi Da vaguely felt that Zhang, the master of the Zhang family, might be his son. Shi Daliao was worried about which one was his son, but Shi Laifeng identified Shi Daliao as a traitor, confronted him and almost killed his father himself. Shi Daliao finally found out the identity of the mysterious man and found that the core of the enemy's R plan was to plunder the rare earth mines in China. In order to cover up Shi Daliang's identity, Li Erqin died heroically. According to Shi Daliang's information, with Zhang's help, our army went through hardships and found a method of blasting ore. The father and son, who have been misunderstood and entangled, joined hands in the final decisive battle, successfully killed Akiyama Jing and shattered the Japanese R plan.
