追踪报道节目「Argon」的组长、记者兼主播金白镇（金柱赫 饰），是一个任何事情都不允许出任何差错的完美主义者，认为事实最重要，并追求正直的报道，尽管如此，由他带领的「Argon」新闻制作组还是从曾经的辉煌跌落到了谷底 。合约制记者李妍华（千玗嬉 饰）只是电视台的合同工，只剩几个月合约期满的她被以“半抛弃”的方式“发配”到了「Argon」小组。偏偏这样一群都在谷底的人，在他们的面前突然发生了一宗大新闻，一个商场在改建地下二层的过程中发生了坍塌，造成了重大人员伤亡，「Argon」所在的电视台因为在新闻速报上已经落后于其他电视台，于是决定用深度分析的访谈节目来切入获取收视率，可是在这个过程里，负责改建工程的现场负责人被急功近利的电视台《晚间新闻》塑造成了不负责任的逃脱者，而敏锐的金白镇则发现了其中并不是那么简单，或许被新闻冠上了“罪人”的人，恰恰是完全无.
