Sai Nam, the younger sister of Police Lieutenant Colonel Saifa, head of a special task force under Police Lieutenant Colonel Phum Buranasilp, tragically dies while on duty during a crackdown on powerful criminal figures. Out of responsibility and grief, Phum resigns from his post to quietly watch over Sai Nam.
Under the alias “her brother,” Sai Nam interacts with others, while Praewa, an orphan, grows up under foster parents involved in drug trafficking. Praewa is forced into prostitution but is rescued when Inspector Yiew raids the criminal operation. She later becomes a member of the Frank Foundation, an organization founded by Mr. Frank to extend influence over Thai society. Praewa is sent to the police academy alongside Sai Nam. After graduation, both are assigned to Inspector Yiew’s unit to investigate the illegal gambling operations of billionaire businessman Phonpipat, a supporter of the Frank Foundation.
The two women infiltrate Phonpipat’s company as bodyguards. Sai Nam repeatedly clashes with Namyen, who appears aloof but secretly assists her in gathering evidence. Sai Nam eventually uncovers proof exposing Phonpipat’s crimes. DTV broadcasts the evidence via CCTV secretly installed in Phonpipat’s gambling den, leading to a police raid. Namyen disappears mysteriously, leaving a message indicating the involvement of “Good Agent,” a vigilante organization founded in collaboration with Phum to expose influential criminals.
Namyen had been planted inside Phonpipat’s company to gather intelligence. Frank’s organization, in response, plans to eliminate Good Agent’s network by planting bombs throughout Bangkok. Phum leads the defusal operations, neutralizing nearly all explosives. Frank’s organization then announces a plan to bomb the government house on New Year’s Day.
Inspector Yiew discovers Praewa’s affiliation with the Frank Foundation and gives her an ultimatum to turn good. However, Yiew is ambushed and killed while delivering a CD to Praewa. When she opens it, she is shocked to hear Yiew confess his love for her.
Sai Nam uncovers the painful truth: Phum, the man she trusted as a kind older brother figure, was responsible for her real brother’s death. Unable to bear it, she resigns from the police force. On New Year’s Day, Phum’s bombing plot to attack the government house is revealed. Praewa exposes Frank’s actions and leads the police to arrest the perpetrators. The final bomb is strapped to Sai Nam. Phum intervenes, risking himself to remove the bomb, but Praewa ultimately seizes it, taking the danger upon herself.
Sai Nam mourns the loss of another dear friend. Together, Phum, Sai Nam, and Namyen continue their mission to spread justice and uphold the ideals of Good Agent.
