DSP Jayaprakash has spent several years looking for David Billa, one of the top internationally wanted criminals. During a chase with the police, Billa is severely wounded and eventually dies. Jayaprakash keeps his death a secret, and finds a doppelganger named Saravana Venu, a petty thief. He asks Venu to infiltrate Billa’s gang, pretending to have amnesia, so that he can learn more about their activities, and gather information that will help the police arrest all the criminals.
