Thiagu is a school teacher by day and a 'Samurai' by night. He and his gang abduct corrupt politicians and bureaucrats who go free because of the loopholes in the legal system. Ofcourse there is a tragic background to all this. Anitha, a schoolgirl is love with Vikram. There is the honest cop Nassar who goes by the rulebook. Cop versus Samurai goes on with finally the Samurai being brought to court.—RC
