Before Dawn

One snowy day, Lee Do-hoon, a human who is half-machine, meets a mysterious man named Yoo Si-cheon. The two witness a gruesome incident in a village where the residents kill one another, and together, they begin a journey to find the culprit. However, the two are different—far too different. Their goal is the same, but their hearts are not. Lee Do-hoon, who appears cold on the outside but is filled with a warm heart and justice, and the somewhat suspicious Yoo Si-cheon. At the end of this long journey, will their conclusion be salvation? Or destruction?
