The story of the little hero Zhang Ga.

During the period of War of Resistance against Japanese Aggression, there was a boy named Zhang Ga in Baiyangdian, central Hebei. He is smart and brave, nicknamed "Ga Kid".

In a Japanese raid, her grandmother was killed to cover the Eighth Route Army, and the Eighth Route Army reconnaissance company commander Zhong was also taken away. Gazi was heartbroken. He decided to take revenge and set out resolutely to find a regional team to fight the Japanese devils. On the way, he mistook Luo Jinbao, the guerrilla platoon leader, for a traitor, wanted to surrender his gun and made a joke.

Later, Ga Xiaozi, as big as a child, disguised himself as a watermelon vendor and paid the fat translator's pistol. In order not to let the captain take the gun back, he hid it in a bird's nest in a tree, so he was criticized and turned off. After the education of the district captain, Gazi realized his mistake.

He was injured in a battle and recuperated in his hometown. When the guerrillas attacked the enemy watchtower, he secretly ran back from his hometown to join the war, but unfortunately he was caught when he went into town for reconnaissance. Gazi was indomitable in the face of the enemy and escaped in the battle. He cooperated with the guerrillas to pull out the watchtower and rescued Zhong Liang.

After the victory of the battle, the district captain praised Gazi on behalf of the troops and rewarded him with a real small pistol. Gazi finally became an excellent little scout.
