Both are brothers...both are police officers but...action is the difference

Ram Lakhan (1989)

Directed by Subhash Ghai

Sharda vows vengeance when her husband is murdered by his two evil cousins, Bhishamber and Bhanu, and she and her two young sons are thrown out on the street. Years after their father's murder, Ram and Lakhan grow up to become policemen. Their personalities are like day and night: while one strives to do what is right, the other often makes poor choices.
