共同警备区是一部剧情片，板门店边界的共同警备区，一天，哨所里的朝鲜士兵（申河均饰）为来路不明的子弹所杀，引发双方枪战。而最有嫌疑的凶手是同在边界上的韩国士兵，但韩国一方却指责是朝鲜先调起事端，双方都认为对手应该对此负责。 为了解决这一无头案件，南北双方同意由一个中立国来进行调查协调。瑞士国籍韩国女孩苏菲（李英爱饰）受派前来调查事件，韩国这边的李秀赫（李秉宪饰）始终保持沉默，而朝鲜一边的幸存者吴敬必（宋康昊饰）却表现出敌意，事情扑朔迷离。随着深入了解，苏菲发现事情隐藏著内幕，现场还另有其人……
In the DMZ separating North and South Korea, two North Korean soldiers have been killed, supposedly by one South Korean soldier. But the 11 bullets found in the bodies, together with the 5 remaining rounds in the assassin's magazine, amount to 16 cartridges for a gun that should normally hold 15. The investigating Swiss/Swedish team from the neutral countries overseeing the DMZ suspects that another, unknown party was involved - all of which points to some sort of cover up. The truth is much simpler and much more tragic.
一句话评论：四个人的警戒？。漫谈《JSA共同警备区》。也谈《共同警备区》。他们的友谊中谁射出了那致命一枪。双方的爱恨纠缠。铸成残酷的是人性还是体制？。令人赞叹的《JSA共同警备区》。结尾是点睛之笔。事件的真实过程。現實未必踐酷，人性尚在人間。
