Gang (Pawalit Mongkolpisit) was born without voice and hearing, and has been living in silence and silence. His special identity made him suffer from bullying from others, and Gang's character became indifferent and autistic. One day, Gang found a job as a cleaner in a shooting club, and met the chivalrous Zu (Pisek Intrakanchit). Zu has been protecting Gang, teaching him how to use firearms and training his physical fitness. The two became close friends and became killers together, wanting to make a big career in the industry. After that, Gang met the beautiful and gentle Fang (Premsinee Ratanasopha), and the two knew each other and loved each other, and their relationship was very good. Just when Gang thought that a happy life was about to come, the bad news came that Zu was killed by his enemies. In grief and anger, Gang could only put aside his feelings with Fang, pick up the cold gun, and avenge his good brother.
