Lee Do-gyeom

A reclusive pawnshop owner goes on a brutal rampage to rescue a young girl kidnapped by a criminal organization.

Chinese secret agent Da-hee receives intel that a large number of illegal firearms are being smuggled into Korea and is sent to investigate the case. She meets Su-han, who is supposed to help her with the case, but due to his lackluster skills they fight over trivial things. But as their witnesses are suddenly murdered, the two of them quickly become the prime suspects.
