影片到最后只有4人到达指定部队报道也是电影的开篇，影片的背景选自于抗美援朝的著名战役，上甘岭战役，这场战斗的程度非常罕见，里面的英雄人物数量很多，这些英雄故事可不可信，在故事中可以了解到断粮断水，弹药匮乏，并且和组织失去了通讯联络，在这样恶劣的条件下，狙击手孙成欢，金川作为志愿军的代表，以血肉之躯来对抗敌人的炮火对抗王牌狙击手一起带领志愿军奋勇杀敌

整场战斗的条件是非常恶劣的，但是中国志愿军可以克服这些困难，有三名战士去找水，但是这三名战士在找到水的时候被敌人狙击手盯住，全部牺牲在电影中，也可以看到我方的狙击手孙成欢被炮弹震晕以后做了一个梦，依稀记得水，要给伤员和而卫生员告诉他，水有很多的时候，他一口就喝了满满，以缸子的水整个战斗的场景是非常激烈的，包括日常的生活，因为有了这些英勇烈士，才有了现在的美好生活。

At the end of the film, only 4 people arrived at the designated troops. The report is also the beginning of the film. The level of fighting is very rare, and there are a lot of heroes in it. These hero stories are not credible. In the stories, it can be learned that there is no food and water, ammunition is scarce, and communication with the organization has been lost. Under such harsh conditions, sniper Sun Chenghuan and Jin Chuan, as representatives of the volunteer army, fought against the enemy's artillery fire with flesh and blood against the ace snipers and led the volunteer army to kill the enemy bravely

The conditions of the whole battle were very harsh, but the Chinese Volunteer Army could overcome these difficulties. Three soldiers went to find water, but this The three soldiers were stared at by enemy snipers when they found water, and they all died in the movie. You can also see our sniper Sun Chenghuan having a dream after being stunned by shells. The hygienist told him that when there was a lot of water, he drank it full in one sip. The whole battle scene with the water in the tank was very intense, including daily life. Because of these heroic martyrs, we have a better life now. .
