Aavanazhi was remade in Kannada as "Anthima Theerpu" starring Ambareesh & Geetha, in Tamil as Kadamai Kanniyam Kattupaadu, in Telugu as Marana Sasanam and in Hindi as Satyamev Jayate. I. V. Sasi made two sequels — Inspector Balram in 1991 and Balram vs. Taradas in 2006.
Balram, popularly known as Karadi, is an honest Circle Inspector. Frustrated in his life after several personal setbacks, including a failed affair of the heart, Balram has turned to drinking and womanizing. Balram is assigned to nab Satyaraj, who evaded the clutches of the police after murdering Chackochan, a contractor. Balram successfully arrests him, but in court, Satyaraj is represented by Advocate Jayachandran . Satyaraj is acquitted by the court, but Balram decides to frame in several other criminal charges pending against him. Usha, Balram's ex-lover, is now married to Jayachandran.
Balram falls in love with Seetha, a prostitute, whom he decides to marry. Meanwhile, Radha, a young lady, is determined to avenge herself on Balram, who she believes to have killed her brother while in police custody. But in reality, it was a handwork of Satyaraj, on instruction from Vincent. Falsely implicated, Balram had been suspended from police for a couple of years, but has been reinstated. Though Seetha tries to convince Radha of the truth, she is not ready to accept it. To gain her revenge over Balram, Radha decides to offer Satyaraj a safe stay away from the police eyes. Balram's open fight with Satyaraj and his "outside the law" dealing with him forms the rest of the story.
