Kim Baek-jin (Kim Joo-hyuk), the team leader, reporter and anchor of the "Argon" news program, is a perfectionist who does not allow any mistakes in anything. He believes that facts are the most important and pursues honest reporting. Despite this, the "Argon" news production team led by him has fallen from its former glory to the bottom. Contract reporter Lee Yeon-hwa (Cheon Seo-hee) is just a contract worker at the TV station. With only a few months left on her contract, she was "semi-abandoned" and "sent" to the "Argon" team. It just so happened that this group of people who were at the bottom of the valley suddenly had a big news story in front of them. A shopping mall collapsed during the reconstruction of the second underground floor, causing heavy casualties. The TV station where "Argon" was located had fallen behind other TV stations in news breaking, so they decided to use in-depth analysis talk shows to gain ratings. However, in this process, the on-site person in charge of the reconstruction project was portrayed as an irresponsible escapee by the quick-success-making TV station "Evening News", and the keen Jin Baizhen discovered that it was not that simple. Perhaps the person who was labeled a "sinner" by the news was precisely a completely innocent or even great self-sacrificer. A war for the news was about to break out.
