In 1980, the Gwangju Incident broke out. Innocent people were massacred by the military government as "red elements", and many families experienced the most painful separation of life and death. The initiator behind all this, Chun Doo-hwan, ascended to the presidency. He stepped down safely a few years later, and was pardoned despite the accusations of military dictatorship and economic crimes. At the same time, the survivors of the Gwangju Incident could no longer sit idly by and watch the greatest injustice in the world. One day in 2006, Shen Meijin (Han Hye-jin), a national shooting team player, Guo Zhenbae, a gangster who served in the military, and Quan Zhenghe, a young policeman, were called together. Their relatives died in the killing 26 years ago, and the former soldier Jin Zhushi who participated in the martial law at that time had hidden huge guilt and hatred in his heart for many years. Now that he has become a big entrepreneur, he decided to work with the survivors to assassinate Chun Doo-hwan, who is still at large and lives a pampered life... This film is adapted from the Korean webtoon of the same name based on the Gwangju Incident.
