Moo Yeol, a taekwondo instructor, falls for Eun Jae at first sight when she comes to his agency and asks for help finding gold treasures. Hee Kyung is a tarot card master, and Yong Soo is a manhwa shop owner who passes his days with no dreams nor hopes, but gets involved in the gold hunting simply for fun. Moo Yeol, Hee Kyung, and Yong Soo gather together at the empty Inquiry Agency office and they discover a dead corpse in the basement. The four of them later decide to start a treasure hunting project.
