The story of Sergeant Songpol or "Hao" (Thanabodi Jaiyen), a young policeman who is determined in his ideals but is framed and becomes a prisoner on "Koh Luem". It is here that Hao gets to know "Amphai" (Chakrit Yamnam) and "Seua Mom" ​​(Somchai Khemklad). Amphai is a former good policeman who was framed, while Seua Mom is a famous, sly but moral tiger. In addition, Hao also gets to know "Miram" (Supicha Sangkachinda), a traveling merchant who dares to do business with the warden on Koh Luem. By chance, Hao learns the secret of the warden and his gang, that these people are pirates who steal from the villagers' cargo ships, causing them to unwillingly become pirates. The first robbery of all of them fails because they cannot stand to see the warden and his gang mercilessly killing people on the boat, causing a fight until the boat sinks. Both sides run for their lives without thinking about their lives. After escaping and reaching the shore, Miram takes them all to her own house. Until the wardens came to seek revenge and caused Miram's mother to die. Miram therefore had to travel with Hao, Amphai and Suea Mom to find her father. Meanwhile, Hao, Amphai and Suea Mom all had the same goal: to seek revenge and settle scores with the triads and the lawless police who had framed them until they were all turned into prisoners.
