Synopsis：In 1945, the Eighth Route Army annihilated the Tenth Puppet Army in Sishui City, killing its commander Rong Ziheng and achieving a major victory. A Japanese reinforcement unit, upon learning of the puppet army's complete destruction, dared not engage and hastily retreated. During their withdrawal, they massacred the entire village of Goshancun, creating the horrifying "Goshancun Massacre." Zhao Chongguang, leading an anti-Japanese detachment of the Eighth Route Army, managed to drive the Japanese forces into a panicked retreat, but this was not enough to expel them from the land. Just as the situation seemed deadlocked, a passionate young man named Zhang Erga changed the battlefield stalemate. He brought Zhao Chongguang news that the Japanese were constructing a second line of defense behind the Yamabe Division, where there was a munitions depot. Only by destroying this depot could the Japanese be thoroughly repelled. However, the Japanese defenses were formidable, with soldiers and guard dogs stationed round the clock near the depot, making the mission extremely challenging. Zhao Chongguang and Zhang Erga quickly formed a special operations team. The battle-hardened Zhao Chongguang took charge of fighting the Japanese, while the clever Zhang Erga, familiar with the terrain, devised the tactics. With clear division of labor and doubled combat efficiency, they set out together with the goal of driving the Japanese out of their homeland. Faced with Japanese aggression, the special operations team remained steadfast, and a brutal, intense battle to defend their land became inevitable.
