It was remade in Kannada as Anthima Theerpu, in Tamil as Kadamai Kanniyam Kattupaadu, in Telugu as Marana Sasanam and in Hindi as Satyamev Jayate.

Satyaraj, an infamous professional killer, assassinates a cement contractor as per the orders of his business rival, Vincent.

Balram, called as "Karadi Balu" is an honest but reputed notorious and arrogant police officer, apprehends Satyaraj within a day.

Jayachandran makes Radha believe that Satyaraj has certain documents implicating Balram in the death of her brother.

During vehicle search, Balram recovers certain incriminating documents and submits the same to his superior officer.

But Balram had already sent a copy of those documents to Central Bureau of Investigation, who arrests the superior officer, Vincent and Adv Jayachandran.

Satyaraj, realising Balram's plan, takes Radha and her friend as hostage and tries to escape.
