The story is set in contemporary South Korea where some 30 years ago, unidentified creatures appeared out of nowhere attacking humans. The ascension of these monsters which are now classified as "Troubles", has resulted in the world falling into chaos. Curiously, along the time of their appearance, a number of humans were born with or able to acquire supernatural abilities. These mutants called the "Trace" are the only ones who can fight off the "Trouble". However, "Trace" are also considered freaks and are mostly shunned by the community due to a few exploiting their powers.

The plot revolves around two main characters: Sa Ghang-gwon, a high school student born as a "Trace" who attempts to hide his ability; the other is Kim Yun-sung, who acquired his "Trace" abilities during his 30s. Soon after his acquisition, his wife and daughter were taken away from him for experimental purposes.
