Modern fitness coach Chen Yu and beauty blogger Su Yao accidentally traveled to the anti-Japanese base area in 1940 and plunged into the war-torn years.
With his strong muscles and fighting skills, Chen Yu rescued Su Yao when the Japanese army was chasing him, and the two joined Zhang Dapao's guerrillas. At first, their arrival was questioned. However, during a battle, Chen Yu turned the tide and Su Yao came up with many clever ideas, successfully winning everyone's trust.
In the team, there are teammates with different personalities such as Zhao Dangdao who charges bravely but is often impulsive and gets into trouble, Zheng Mulu who is confused and forgetful but honest and honest, Sun Jiiling who cleverly delivers information, and Qian Abacus who is meticulous in managing logistics. Everyone fights side by side, and there are many situations during this period. The Japanese Colonel Yamamoto is cunning and cruel, while the adjutant Kameda is as cowardly as a mouse, causing a lot of trouble for the team.
During a Japanese encirclement and suppression campaign, Zheng was confused and forgot to bring key documents. Fortunately, the clever Sun Jiiling came to the rescue; when Zhou Xiucai was seriously injured, the eccentric but highly skilled Dr. Lin came back to life. In the final battle, everyone worked together and successfully defeated the Japanese army. The Yamamoto Wolf was killed, and Kameda was persuaded to surrender.
After the victory of the Anti-Japanese War, Chen Yu and Su Yao were summoned by mysterious power to return to modern times. The war years, full of passion, laughter and emotion, became the most unforgettable memories of their lives.
