The Twelve Zodiacs(2003)

The Twelve Zodiacs follows Lieutenant Jeng, a suspended cop seeking revenge against drug dealer Yai, who murdered his best friend and fellow officer. When Jeng goes undercover without authorization, his reckless approach backfires—the suspects escape, and Yai turns the tables by suing the police station for assault and attempted murder. Now on probation and sidelined from active duty, Jeng is reassigned to investigate a suicide case. Trapped between his hunger for justice and the constraints of his suspension, he must navigate a dangerous investigation that could either redeem his career or destroy it entirely. This Thai crime drama explores themes of vengeance, duty, and the thin line between justice and obsession.
