Best friends who steal for a living. When they try to steal from a scientist, One of them falls trap to one of his scientific experiments, transforming him into a woman.

Three friends Karnan (G V Prakash Kumar) a thief, Kalai (Pasanga Paandi) an ex-convict and Rocky (Nandhan Ram) a drug peddler are childhood friends who live in the government housing board complex in Thuraipakkam, Chennai. The police and the public always eye those in the area as criminals and jobs are denied, forcing them to resort to illegal activities. Rocky is always at loggerheads with a rival gang of drug peddlers. How that triggers a chain of events that spell disaster to the three friends and their families and how a corrupt cop uses them for his own gains is what the rest of the screenplay is all about.
