Bayam Ariyan, by debut direcotr Pradeesh, is yet another tale of how a cop misuses innocent youngsters for personal gain.

Koni (Mahesh Raja) and Unni (Manikandan) are buddies who are part of the criminal underbelly of the city. Their job: To bump off certain elements under inspector Mithran (Kishore). These murders earn them a plentiful supply of cash, which they blow on wine and women.

One day Koni comes across Nivedhitha (Udhayathara) and falls in love with her at first sight. After a few initial mix-ups she concludes that Koni is a nice chap and begins to reciprocate his feelings. Gradually, Koni wants to turn over a new leaf after meeting Nivedhitha.

Meanwhile, Mithran gets into a predicament and faces the wrath of the commissioner of police (Mohan). An irked Mithran hatches a plot to bump off the top boss himself and entrusts the job to Unni, who now operates separately. However, the commissioner escaoes the attempt on his life. In order to save his skin, Mithran hudes Unni at his molested his beloved wife while he was away. He kills Unni in a staged encounter.

Next his anger turns towards Koni. The rest of the story is narrated in a crude and crass manner. Mahesh Raja as a ruthless thug is totally convincing, but an educated, upper-class Udhayathara falling for a criminal doesn't ring true. The real scene-stealer is Kishore, who has underplayed his part and done well. Had the director reduced the blood and gore, the movie would have been appealing.
