In June 1950, soon after the start of the Korean War, a troop of North Korean soldiers enter a small South Korean village. Captain Jeong-woong proclaims that they came to liberate the villagers but their true agenda is to ferret out the reactionaries. The villagers and Seol-hee, who is separated from her fiance on her wedding day, offer them heartfelt hospitality and cooperation to avoid falling out of the army’s favor. Eventually friendships starts to build up between the soldiers and the villagers.

The Plan Man is about a man who lives everything according to plan until he meets a woman who wasn’t a part of it.

On the day the 15-year statute of limitations expired on a high profile serial murder case that claimed the lives of 10 women, a family member of the victim throws himself off the building in front of Choi Hyeong-goo, the detective in charge of the case. Two years later, a man called Lee Doo-seok publishes a book titled “I am the Murderer” claiming responsibility for the murders that took place 17 years ago. His book becomes a bestseller because of the author’s charming looks and his vivid depiction of the crime. The detective and the self-proclaimed murderer meet face to face on a television debate show. Believing that Lee is nothing but a con artist, Detective Choi renews his search for the ultimate truth. Then another man appears suddenly, claiming he is the real killer.
