Hong Gil Dong (Lee Je Hoon from Tomorrow With You and Signal) is a vigilante detective. Along with President Hwang (Go Ah Ra from Hwarang), he runs an illegal detective agency that can track down anyone within the hour. Hwang runs the agency to fulfill her father’s wishes and stop evil, but Hong Gil Dong’s only goal is to find the one person even he can’t track down: the man who killed his mother.
