The Big Gun 3

The story follows “Kamnan Suea”, also known as Nam Phet (Yanisa Theerathorn), who governs Don Rak Subdistrict with dedication and genuine concern for the villagers’ hardships. Thanks to her efforts, Don Rak has remained peaceful and free from crime for many years. But one day, a gang of iron-mask bandits boldly robs a money transport vehicle. Although Kamnan Suea and “Kamnan Chang,” or Kachen (Phoolpat Attapanyapol), the headman of Don Ratom Subdistrict, try to stop them, the gang ultimately succeeds in escaping with 100 million baht.
Chaya (Phonphoj Phunnil), a relative of Kamnan Chang and the grandson of the owner of a security company, is then sent to recover the missing 100 million baht. He is given one strict condition: if he cannot get the money back within two months, he must never set foot in the company again.
Soon after, Khunphon (Warakorn Sawasakorn) arrives to take up the post of the new district chief. However, for his own safety, he does not immediately reveal his true identity. He also intends to investigate the person who murdered District Chief Khemakorn (Phonlarat Rodraksa), his father. After Khemakorn died in the line of duty, several other district chiefs also died under mysterious circumstances. Khunphon is certain that the same killer is responsible for all of them.
Khunphon begins investigating the deaths of his father and the other district chiefs, setting his sights on Kamnan Suea’s family. He tries to get close to Kamnan Suea, aided by his older friend and partner Kamnan Chang, who is secretly seeing Nam Mon (Supitchaya Srisawat), and by Chaya, who is secretly courting Nam Nuea (Kanyanatsinee Srapmee), Kamnan Suea’s younger sister. But all three young men must face the fierce protectiveness of Khun Thip (Nataya Chanrung), the mother of the three sisters, as well as Kamnan Suea’s own protectiveness toward her younger siblings. Kamnan Suea distrusts Kamnan Chang because he is a widower with a child, while Chaya is dismissed as unreliable and weak. As a result, both Khun Thip and Kamnan Suea do everything they can to obstruct the men, nearly driving them to despair. Still, the three men do not give up, especially with help from Nid (Niyada Sriboonsom), the nanny of Nam Mon and Nam Nuea, who secretly plays matchmaker for them.
The beauty of Nam Mon and Nam Nuea, Kamnan Suea’s younger sisters, is famous far and wide, and they attract many admirers. Whenever the two young women go to sell fruit at the market, they are surrounded by suitors. One of them is Khunchai Meng (Nawabodin Sanhawanphakdee), the son of Sia Kwang (Waratanaphot Tantiviriyangkul), an influential figure in Don Ratom. But Khunchai Meng is already engaged to Daranee (Patcharawalai Pongphamon), the daughter of Godfather Decha (Pongsanart Winsiri). Daranee is openly jealous and frequently causes trouble with Nam Nuea at the market.
While Khunchai Meng pursues Nam Nuea, Phuyai Hiam (Surasak Chotthinwat) is trying to court Nam Mon. He truly likes her, but he also has another motive: he wants to gain control of Kamnan Suea’s land, which borders his own, so he can sell it to his boss, Godfather Decha. Decha wants Kamnan Suea’s land in order to build a natural gas and oil production plant.
But Decha wants more than just Kamnan Suea’s land — he also wants to expand his power across the district. So he encourages Phuyai Hiam, who dreams of becoming a subdistrict headman himself, to keep sending people to harass Kamnan Chang and Kamnan Suea. What Hiam does not realize is that Decha never truly intends to give him the position. Decha is simply using everyone around him to build his influence over Don Ratom and eventually over Don Rak as well.
Will Khunphon, Kamnan Suea, Kamnan Chang, and Chaya succeed in recovering the missing 100 million baht? And how will the new district chief, Khunphon — with the cooperation of the two headmen — protect the district from the grip of the powerful Godfather Decha?
