The Brave Man

Thongdee was transferred to Ban Huai Jorakhe after opposing a crime backed by a powerful figure. There, he meets Ploy, the daughter of Preecha, whom Thongdee suspects of being involved in illegal activities. Ploy, disillusioned with the police, believes there are no good cops left and fights for justice and equality against powerful criminals. When Thongdee learns of his superior's corruption, he realises he must battle both the criminals and the corrupt officers.
