A corrupt police inspector Pandiya (Natraj) and upright sub inspector Nandha (Nandha) are at logger heads, the former always dominates the latter as he is the superior officer. At one point of time, Pandiya turns honest and even files a case against the son of the most powerful politician in the town Periyanna. But sadly Nandha still believes that Pandiya is corrupt and suspects him in the murder of another cop friend. Mean time, due to the earlier ego clash Nandha becomes Periyanna's right hand and sketches a plan to encounter Pandiya.
