Moo Yeol is a taekwondo instructor who falls for Eun Jae at first sight when she comes and asks him to help her find gold treasures at the agency. 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.

This is also a drama without a love story.
