Ze zeggen dat wat je niet doodt, je sterker maakt, maar dat is niet het geval voor ‘s werelds zwakste jager Sung Jinwoo. Nadat hij op brute wijze was afgeslacht door monsters in een hooggeplaatste kerker, kwam Jinwoo terug met het Systeem, een programma dat alleen hij kon zien en dat hem in alle opzichten een niveau hoger brengt. Nu is hij geïnspireerd om de geheimen achter zijn krachten te ontdekken en de kerker waaruit ze voortkomen.
