Een officier moet de aanvallen van een mysterieuze huurmoordenaar verijdelen. De voormalige onderzeeboot commandant Do-yeong krijgt een anonieme chantage oproep: overal in de stad zijn explosieven verborgen, waarvan de ontstekers reageren op geluid. Do-yeong haast zich van de ene plaats naar de andere om ze onschadelijk te maken. Maar de bommen legger is altijd een stap voor.
