1947年随着炮火的不断推进，阳泉获得解放，中国共产党在一片废墟上建立了自己的城市，成为中国共产党领导创建的第一座人民城市。全片以建设城市为主线，以清除敌特和个人情感为副线，叙写了为全国其他城市解放建市提供借鉴的阳泉解放建市历程。塑造了以任功、刘水河为代表的共产党人在创建人民城市过程中所表现出来的革命英雄主义精神和不忘初心、牢记使命的责任担当。

With the continuous advancement of artillery fire in 1947, Yangquan was liberated, and the Chinese Communist Party established its own city in ruins, becoming the first people's city created by the leadership of the Chinese Communist Party. The whole film takes the construction of the city as the main line, with the elimination of enemy agents and personal emotions as the secondary line, and narrates the liberation and construction of Yangquan as a reference for other cities across the country. It has shaped the revolutionary heroism of the Communists represented by Ren Gong and Liu Shuihe in the process of building the people's city, and the responsibility of not forgetting the original intention and keeping the mission in mind
