In 1925 Korea, Japanese rulers demand the last remaining tiger be killed. The tiger easily defeats his pursuers until a legendary hunter takes him on.

The story takes place in Seoul, 2011. Lee Yoon-sung is a talented MIT-graduate who's working on the international communications team at the Blue House. He encounters dangerous situations while solving a variety of cases, both big and small, for people who need his help, and eventually becomes a "city hunter."
