An Agent from the future comes to the past to prevent crimes. The only way for him to return to the future is simply to wait. During this time, he must live in complete isolation. This would drive most men insane, but it suits the solitary agent just fine... until one day, when he runs into a girl about to commit suicide.

Han Wu-song, an antique collector, gets killed while appraising a bronze horse rider statue which trader Wang Dae-in has stolen from a tomb. Dae-in dies on the scene and Wu-song leaves the killer's name on the cave wall before he dies. Dae-in's son Wang Gak thinks Wu-Song killed his father and fights with his son Jung-pa. Trader Kwan and her daughter Mi-ryung stop the fight. Jung-pa and Mi-ryung's love is disturbed by Ju-yang. Gak and Jung-pa chase him to find Wu-song's body with Ju-yang's name on the wall but Mi-ryung appeals them not to kill...
