The Dilip Kumar - Sanjay Dutt starrer 'Kanoon Apna Apna', explores the relationship between a father and son who believe in different ideologies. Jagat Pratab Singh (Dilip Kumar) is a collector and a staunch believer in law and order. On the other hand, his son Ravi (Sanjay Dutt) has always witnessed the law being violated by criminal practices and thus concludes that if law must be protected then we must take help of illegal means. The tension seems to take an upswing in the father-son relationship when Ravi's friend gets murdered by the son of a corrupt minister (Kader Khan), who eventually manages to escape the law too. Will Ravi now fight an open war for his friend's justice and challenge his father's legalism? Come, let's find out.
